Work Step by Step

For cross multiplication, we know: $$\frac{a}{d} =\frac{b}{c} \rightarrow ac=bd$$ Thus, we find: $$3\left(x+2\right)=x\cdot \:4\\ 3\left(x+2\right)=x\cdot \:4\\ x=6$$ Checking our solution by plugging the given value back into the equation, we assure that the solutions are not extraneous.
