Question

Find the value of ‘m’ in 3m+12=15​

Answer 1

3 m+ 12 = 15

⇔3 m= 3

⇔m= 1

Answer 2

`\sf3m + 12 = 15 \\ \sf3m = 15 - 12 \\ \sf3m = 3 \\ \sf \: m = (3)/(3) \\ \sf \: m \: = \underline{ \bf \: 1}`

-> Just move all the numbers from the left side to the right side until only the variable is left. Then you can solve the equation & find the required value.
