What is the value of x when -3x + 7x = -12?
i just want to make sure my steps are in the right direction on this.

-3x + 7x = -12

(-3 + 7)x = -12

4x = -12   (divide 4 from each side)

4x/4 = -12/4

x = -12/4

x = 3 <-answer

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
