Answer: x=3
Step-by-step explanation:
5x+7=-3x31
5x+7-7=3x+31-7
subtract the numbers
5x=-3x+24
add 3x to both sides
5x=-3x+24
5x+3x=3x+24+3x
combine like terms
8x=24
divide both sides of the equation by the same term 8x=24
8x/8 = 24/8
cancel terms that are in both numerator and denominator
divide the numbers
x=3
