Question

19 if 3(x + 2)-2(x + 1)=8, the value of x is 1) 1 2) $\frac{1}{5}$ 3) 5 4) 4

Explanation:

Step1: Expand the expressions

$3(x + 2)-2(x + 1)=3x+6-(2x + 2)=3x+6 - 2x-2$.

Step2: Simplify the left - hand side

$3x+6 - 2x-2=(3x-2x)+(6 - 2)=x + 4$.

Step3: Solve for x

Set $x + 4=8$, then $x=8 - 4$.

Answer:

4
