Answer

$x=2$.

Work Step by Step

The given equation is $\Rightarrow 26-4x=9x$ Add $4x$ to both sides. $\Rightarrow 26-4x+4x=9x+4x$ Simplify. $\Rightarrow 26=13x$ Divide both sides by $13$. $\Rightarrow \frac{26}{13}=\frac{13x}{13}$ Simplify. $\Rightarrow 2=x$. Check:- $\Rightarrow 26-4(2)=9(2)$ $\Rightarrow 26-8=18$ $\Rightarrow 18=18$ True. Hence, the solution is $x=2$.
