Math, microeconomics or criminal justice
5(2x-8) + 15 = -15
expand the parentheses
10x-40 +15 = -15, combine 15 and -45
10x -25 =-15
add 25 to both sides
10x = -15+25 = 10
10x = 10 divide by 10
x = 1
check the solution by plugging 4 for x in the original equation
5(2x-8) + 15 = -15
5(2(1)-8) +15 =-15
5(2-8) +15 =-15
5(-6) + 15= -15
-30 + 15 = -15
-15 = -15
