#### Answer

The solution is 0

#### Work Step by Step

4-7m = -3m +4 Subtract 3m to both sides
4-7m +3m= -3m +4 + 3m Simplify
4-3m=4 Subtract 4 to both sides
4-3m-4=4-4 Simplify
-3m=0 Divide both sides by -3
$\frac{-3m}{-3}$=$\frac{0}{-3}$
m=0
The solution is 0
Check
4-7m =-3m +4
4-7$\times$0 =-3$\times$0+4
4-0=0+4
4=4
