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
__ = __
10 10
cancel terms that are in both the numerator and denominator.
...( divide the numbers)
x = 3
Solution: x = 3
