AI Thread Summary
To solve the equation 4x + 6 = -10, first isolate the term with x by subtracting 6 from both sides, resulting in 4x = -16. Next, divide both sides by 4 to find x = -4. The confusion arises from the negative value on the right side, but the steps to isolate x remain consistent regardless of the signs. Understanding the arithmetic operations involved clarifies the solution process. The final answer is x = -4.

Doesn't $4x+6=-10$ imply that $4x=-10-6=-16$ ?
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Midpoints'

Just chatting with my son about Maths and he casually mentioned that 0 would be the midpoint of the number line from -inf to +inf. I wondered whether it wouldn’t be more accurate to say there is no single midpoint. Couldn’t you make an argument that any real number is exactly halfway between -inf and +inf?
