The solution is 1

Work Step by Step

4-7m=-3m Subtract 4 from both sides 4-7m-4=-3m -4 Simplify -7m= -3m-4 Add -3m from both sides -7m+3m= -3m-4+3m Simplify -4m=-4 Divide by -4 on both sides $\frac{-4m}{-4}$=$\frac{-4}{-4}$ m=1 The solution is 1 Check 4-7m=-3m 4-7$\times$1=-3$\times$1 Multiply 4-7=-3 -3=-3
