An equation is shown.
18+ 5(2x + 5) = 12
solve the equation for x.

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

x= -31/10 or x= -3 1/10

all but the second one
