Question

Find the value of x:

(a) 9x+6=8-2x
(b) 2x-1=14-x
$\left(c\right)2x+\frac{5}{3}=\frac{26}{3}-x$

Answer 1

Dear student,

$$\begin{gathered} 1a)9x+6=8-2x \\ \Rightarrow 9x+2x=8-6 \\ \Rightarrow 11x=2 \\ \Rightarrow \boxed{x=\frac{2}{11}} \\ b)2x-1=14-x \\ \Rightarrow 2x+x=14+1 \\ \Rightarrow 3x=15 \\ \Rightarrow x=\frac{15}{3} \\ \Rightarrow \boxed{x=5} \end{gathered}$$
