Question

Solve the equation by transposition of terms: 2m + 5 = 3 (3m - 10)
PLS TELL WITH STEP BY STEP EXPLANATION​

Answer 1

2m + 5 = 3 (3m - 10)

2m + 5 = 9m - 30

2m - 9m -5 + 5 = -5 - 30 + 9m - 9m

-5 and +5 from LHS (Left hand side) + 9m and - 9m on RHS (Right Hand Side) will cancelled out!!

So,

2m - 9m = -5 - 30

-7m = -35

(-) sign will cancelled out

m = 35 / 7

m = 5
