Question

Solve the following equations by systematic method2m-12=18

Answer 1

Given:

`2m-12=18`

Solve the equation by systematic method,

`\begin{gathered} 2m-12=18 \\ \text{Add 12 on both sides} \\ 2m-12+12=18+12 \\ 2m=30 \\ \text{Divide both sides by 2} \\ (2m)/(2)=(30)/(2) \\ m=15 \end{gathered}`

Answer: m = 15
