Question

Which value of x is the solution of the equation 2(x - 4) + 7 = 3?

Answer 1

x=2

Explanation:

2(x-4)+7=3

First, multiply the 2 to x-4.

2x-8+7=3

Simplify.

2x-1=3

Add x on both sides.

2x=4

Divide 2 on both sides.

x=2

Answer 2

`\begin{gathered} 2(x-4)+7=3\rightarrow \\ 2x-8+7=3 \\ 2x-1=3 \\ 2x=3+1=4 \\ x=(4)/(2)=2 \end{gathered}`

so the answer is x=2
