Ответ:
X=-3
Step-by-step explanation:
Subtract 8 from both sides of the equation.
7x+8=3x-4
7x+8-8=3x-4-8
Subtract the numbers.
7x=3x-12
Subtract 3x from both sides of the equation.
7x=3x-12
7x-3x=3x-12-3x
Combine like terms.
4x=-12
4x/4=-12/4
Cancel terms that are in both the numerator and denominator, then divide the numbers.
X=-3
