Answer

The solution is $x=2$.

Work Step by Step

The given equation is $\Rightarrow -\frac{3}{2}x-2=-4x+3$ Write a system of linear equations using each side of the original equation. $\Rightarrow y=-\frac{3}{2}x-2$ ...... (1) $\Rightarrow y=-4x+3$ ...... (2) Use the graph. The intersection point is $(2,5)$. Check: $\Rightarrow -\frac{3}{2}x-2=-4x+3$ $\Rightarrow -\frac{3}{2}(2)-2=-4(2)+3$ $\Rightarrow -3-2=-8+3$ $\Rightarrow -5=-5$ True. Hence, the solution is $x=2$.
