For values of x which a solution exists solve for y

In summary, the conversation discusses the concept of "For values of x which a solution exists," which refers to specific values of x that can be substituted into an equation to find a solution for y. To determine if a solution exists, one must substitute the given value of x into the equation and solve for y. Multiple solutions can exist for a given value of x, and to solve for y, one must manipulate the equation using algebraic rules. If there is no solution for a given value of x, it means that no value of y can make the equation true.

Homework Statement


(For those values of x for which a solution exists), solve the following equation for y
3e^(2y−8) = (2x^5)−3

Homework Equations


1. xln e= x

The Attempt at a Solution


1.3e^(2y−8) = (2x^5)−3
2.e^(2y−8) = ((2x^5)−3)/3
3.(2y-8)ln e = (ln (2x^5)-3)/3
4.(2y-8) = (ln (2x^5)-3)/3
5.y= ((ln (2x^5)-3/6)+8

this answer was wrong just wondering where i went wrong??

[tex]e^{2y-8}=\frac{2x^{5}}{3}-1[/tex]

[tex]2y-8=ln({\frac{2x^{5}}{3}-1})[/tex]

[tex]2y=ln(\frac{2x^{5}}{3}-1)+8[/tex]

[tex]y=\frac{ln(\frac{2x^{5}}{3}-1)}{2}+4[/tex]

1. What does "For values of x which a solution exists" mean?

This means that there are certain numbers that can be substituted for x in the given equation or problem that will result in a solution for y. In other words, there are specific values of x that will make the equation true.

2. How do I determine if a solution exists for a given value of x?

To determine if a solution exists, you need to substitute the given value of x into the equation and solve for y. If the resulting value of y is a real number, then a solution exists. If the resulting value of y is undefined or a complex number, then no solution exists.

3. Can there be more than one solution for a given value of x?

Yes, there can be more than one solution for a given value of x. This is often the case for equations with multiple variables or for systems of equations. In these cases, there may be multiple values for y that make the equation true for a given value of x.

4. How do I solve for y when a solution exists?

To solve for y, you need to follow the rules of algebra and manipulate the equation to isolate y on one side of the equals sign. This may involve combining like terms, distributing, or using inverse operations. Once y is isolated, you can solve for its value using basic arithmetic.

5. What if there is no solution for a given value of x?

If there is no solution for a given value of x, it means that there is no value of y that can make the equation true. This could be due to a variety of reasons, such as the equation being undefined for that value of x or the equation being contradictory. In these cases, the solution set would be empty or "no solution."
