Question

Arrange the steps of solving for the equation $2(2x+5)-7=11$

• A. $2(2x+5)=18$
• B. $(2x+5)=9$
• C. $2x=4$
• D. $x=2$

Answer 1

Given, $2(2x+5)-7=11$
$\Rightarrow 2(2x+5)=11+7$
$\Rightarrow 2(2x+5)=18$
$\Rightarrow (2x+5)=\frac{18}{2}$
$\Rightarrow (2x+5)=9$
$\Rightarrow 2x=9-5$
$\Rightarrow 2x=4$
$\Rightarrow x=\frac{4}{2}$
$\Rightarrow x=2$
