first u get both sides to match in varibles .........so factor in the 2 .....2*4m =8m... and 2*-5=-10 ... which gives u 8m-10



now u have 3m-10=8m-10

next get the same varibles on the same side

3m-10=8m-10
-3m

-10=5m-10

same thing for other side

-10=5m-10
+10

0=5m
➗
both sides by 5

should get m=0
