Question

3m - (m + 4) + 2(2m - 9) - m = 13, then m = ?​

Answer 1

Answer:

3m -(m+4)+ 2 (2m-9)-m=13

=>3m - m+4+4m-18-m=13

=>2m+4m-m= 13+ 18-4

=>6m= 27

=>m=27/6

=>m=9/2

=>m=4.5( Ans)

Answer 2

The value of "m" will be "7". Further explanation is given below.

Step-by-step explanation:

Given equation is:

3m-(m + 4)+2(2m-9)-m= 13

On solving the above equation, we get

⇒ 3m-(m+4)+(4m-18)-m= 13

⇒ 3m-m-4+4m-18-m= 13

⇒ 3m-m+4m-m= 13+4+18

⇒ 2m+3m= 35

⇒ 5m= 35

⇒ m= $\frac{35}{5}$

⇒ m= 7
