Question

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

Answer 1

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

Answer 2

Hey!

------------------------------------------------

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

------------------------------------------------

Answer:

`\large\boxed{x~=~-3.1}`
