Sagot :
let's check
3m - 9 = 9+3m
collect like terms
3m -3m = 9 + 9
0m = 18
which is not possible, so it will not have any solutions
3m - 9 = 9+3m
collect like terms
3m -3m = 9 + 9
0m = 18
which is not possible, so it will not have any solutions
3m - 9 = 9 + 3m
-3m -3m
0m - 9 = 9
+9 +9
0m = 18
0 0
m = 0
B. no solution
-3m -3m
0m - 9 = 9
+9 +9
0m = 18
0 0
m = 0
B. no solution
