y=1/5(2)4x-7

Equation 2

y=1/10(1/2)9-3x


The Attempt at a Solution




Made them equal each other got rid of the 1/5 one one side and it made the 1/10 turn into 1/2 and now i dont know what to do so I got

I think you need more parentheses! Is this 24x - 7 = (1/2)(1/2)9 - 3x?

If you don't know how to use superscripts for exponents, at least put parentheses around exponents with multiple terms.

Am I happy that you can quote what I did? Not so much that I'm doing cartwheels or anything.

Can you simplify a*ab?

Also, 2x = (1/2)-x.

These hints should help you write your equation so both sides use the same base.
