Question

If the first step in the solution of the equation -8 - 7x = -5x - 10 is "add 10," then what should the next step be?
a.add 5x
b.add 7x
c.add 8

Answer 1

the way i do is:

-8 -7x = -5x -10

i bring all the variables to one side and the numbers to the other
so

-8 + 10 = -5x + 7x

2 = 2x

2/2 = 2x / 2

1 = x

Answer 2

i think the answer is b
