Question

I need help with question 9

Answer 1

3x-10=7x+2 First you have to subtract 2 from both sides

3x-12=7x Then subtract 3x from both sides

-12=4x Lastly, divide both sides by 4

And the answer is X=-3

Answer 2

3x-10=7x+2
Subtract 2 from both sides
3x-12=7x
Subtract 3x from both sides
-12=4x
Divide both sides by 4
X=-3
Hope this helped:)
