To solve for m, we must isolate m:
(5-4m)/3 = -7
Multiply both sides by 3:
5-4m = -21
Subtract 5 from both sides:
-4m = -26
Divide by -4:
m = 13/2 = 6.5

-3+x=7. x=10
-3
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
2x+3 = 7 2x = 7-3 2x = 4 x = 2
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
