Answer 1

$\huge{ \underline{\underline{\mathrm{ \red{Question}}}}}$

3(5x-2)-8(2x - 7) = 9

$\huge{ \underline{\underline{\mathrm{ \red{Answer}}}}}$

3(5x-2)-8(2x-7)=9

We move all terms to the left:

3(5x-2)-8(2x-7)-(9)=0

We multiply parentheses

15x-16x-6+56-9=0

We add all the numbers together, and all the variables

-1x+41=0

We move all terms containing x to the left, all other terms to the right

-x=-41

x=-41/-1

x=+41

Answer 2

Answer:

$3(5x - 2) - 8(2x - 7) = 9 \\ \\ 15x - 6 - 16x + 56 = 9 \\ \\ - x + 50 = 9 \\ \\ - x = 9 - 50 \\ \\ - x = - 41 \\ \\ x = 41$
