Answer:

5(x - 10) = 30 - 15x

We distribute 5 (x-10)

So 5x-50 = 30 -15x

5x+15x=50+30

(-15x became 15x because we brought it back to the other side and -50 became 50 because we brought it back to the other side to put the x's with the x's and the digits with the digits.)

So 20x=80

x= 50/20

We simplify 80/20

So x=4

Answer:

x = 4

Explanation:

We can first expand 5(x-10), getting 5x - 50.

Thus, 5x - 50 = 30 - 15x

We can then isolate x, getting (5+15) x = 30 + 50

20 x = 80

x = 4.
