Multiply both sides by .8
cross%28.8%29%284m%2Fcross%28.8%29%29+=+-7%28.8%29
...
4m = -5.6
...
Divide both sides by 4
highlight_green%28m+=+-5.6%2F4%29
...
Alternatively,
in on step
4m%2F.8+=+-7
Multiply both sides by .8%2F4
%28.8%2F4%29%284m%2F.8%29+=+-7%28.8%2F4%29
...
m = -5.6%2F4

Multiply both sides by 0.8 to get

4m/0.8=-7

4m = -7*0.8

4m = -5.6

Then divide both sides by 4 to completely isolate m

4m = -5.6

m = -5.6/4

m = -1.4


So the solution is m = -1.4
