Question 995542: 3+5(8-2x)=63
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! 3 + 5 * (8-2*x) = 63
remove the parentheses to get:
3 + 5*8 - 5*2*x = 63
simplify to get:
3 + 40 - 10*x = 63
combine like terms to get:
43 - 10*x = 63
subtract 43 from both sides of the equation to get:
43 - 10*x - 43 = 63 - 43
combine like terms to get:
-10*x = 20
divide both sides of the equation by -10 to get:
-10*x/-10 = 20/-10
simplify to get:
x = -2
replace x in the original equation with -2 to get:
3 + 5 * (8-2*x) = 63 becomes:
3 + 5 * (8 - 2*-2) = 63 which becomes:
3 + 5 * (8 + 4) = 63 which becomes:
3 + 5 * (12) = 63 which becomes:
3 + 60 = 63 which becomes:
63 = 63 which confirms the solution is correct.
