Can someone also explain how to get the answer thank u

Answer:

m = -\frac{194}{3}

Step-by-step explanation:

I'm assuming you are trying to find m. In order to do so, you need to get m on one side.

Before doing that let's multiple -2 and -3m by \frac{4}{3}

256=-\frac{8}{3} - 4m

add -\frac{8}{3} to both sides

258\frac{2}{3}=-4m

I would get rid of the fraction so I'd multiply both sides by \frac{3}{1}

\frac{776}{3}*3 = 4m*3

776=-12m

divide both sides by -12m

m = -\frac{776}{12}

which can be simplified to

m = -\frac{194}{3}

ALL UNLESS THAT \frac{4}{3} IS A POWER
