Question

7m+19/2=13 solve and verify this question
​

Answer 1

7m+19/2=13 -Given

7m+9.5=13
7m=13-9.5
7m=3.5
m= 3.5/7
m=0.5

Answer 2

$7m + \frac{19}{2} = 13 \\ = > 7m = 13 - \frac{19}{2} \\ = > 7m = \frac{26 - 19}{2} \\ = > 7m = \frac{7}{2} \\ = > m = \frac{7}{2 \times 7} \\ = > m = \frac{1}{2}$

Verification :

LHS-

$7m + \frac{19}{2} \\ = 7 \times \frac{1}{2} + \frac{19}{2} \\ = \frac{7}{2} + \frac{19}{2} \\ = \frac{7 + 19}{2} \\ = \frac{26}{2} \\ = 13$

RHS-

$13$

LHS=RHS

Hence proved.
