Question

I need help finding x!

Please show work for both!

Answer 1

1. Answer x=-5
You would subtract 25 from each side of the equal sign, taking 25 away from 40 and 25 away from 25, isolating the x. So you would then have -3x=15. You would then divide each side by -3, and getting x=-5

Answer 2

1. -5

2. -2

Explanation:

1. 25-3x=40

-25 -25

-3x=15

/-3 /-3

x=-5

2. 1/3(x-10)=-4

1/3x=-4

x3 x3

x-10=-12

+10 +10

x=-2
