Respuesta :
18+ 5(2x + 5) = 12
mutiply the bracket by 5
(5)(2x)=10x
(5)(5)=25
18+10x+25=12
18+25+10x=12
43+10x=12
move 43 to the other side
sign changes from +43 to -43
43-43+10x=12-43
10x=12-43
10x=-31
divide both sides by 10 to get x by itself
10x/10= -31/10
Answer:
x= -31/10 or x= -3 1/10

Steps To Solve:
18 + 5(2x + 5) = 12
~Distributive Property
18 + 10x + 25 = 12
~Combine Like Terms
43 + 10x = 12
~Subtract 43 to both sides
43 + 10x - 43 = 12 - 43
~Simplify
10x = -31
~Divide 10 to both sides
10x/10 = -31/10
~Simplify
x = -3.1
