Question

What is the solution of 4(x - 10) = -3x - 12?

Answer 1

Answer:The x would be 4

Explanation:

You first distribute 4(x-10)=-3x-12

4x-40=-3x-12

Add 40 to both sides

Simplify

Add 3x to both sides

divide both sides by the same factor

the simplify

then your answer would be 4

x=4

Answer 2

`4(x-10)=-3x-12`

first solve the parenthesis

`4x-40=-3x-12`

then, place the x's on the same side and the other numbers on the other side

`\begin{gathered} 4x+3x=-12+40 \\ \end{gathered}`

do the operations

`7x=28`

solve x

`\begin{gathered} x=(28)/(7) \\ \\ x=4 \end{gathered}`

the value of x is 4

you can check the solution replacing x on the initial expression

`4((4)-10)=-3(4)-12`

and solve each side

`\begin{gathered} 4(-6)=-12-12 \\ -24=-24 \end{gathered}`

the equality is right
