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
