Answer:
[tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
We're trying to make the coefficient of [tex]x[/tex] 1, so that we can have x is equal to something.
We'll find the required number:
[tex]\frac{1}{-\frac{3}{4}}\\\\=1*(-\frac{4}{3})\\\\=-\frac{4}{3}[/tex]
We'll check this works: [tex]-\frac{3}{4}*(-\frac{4}{3})=1[/tex].
