18-12=-7x-3x

6=-10x

x=6/-10

Answer 2

Answer:

3x -12 = -7x + 18

...(Adding 12 in both sides of the equation)

3x -12 = -7 + 18

3x - 12 + 12 = -7 + 18 + 12

3x = -7x + 30

...( Adding 7 on both sides of the equation)

3x = 7x + 30

3x + 7x = -7x + 30 + 7x

combine like terms

10x = 30

...(Divide both sides by the equation by the same term)

10x = 30

10x 30

__ = __
