Question

7m+12= -4m + 78 with verification

Answer 1

$\tt {\underline{ \underline{ \purple{✠Answer:-}}}}$

$\tt{7m + 12 = - 4m + 78}$

$\implies \tt{7m + 4m = 78 - 12}$

$\implies \tt{11m = 66}$

$\implies \tt{x = \frac{66}{11} }$

$\implies \bf \red{x = 6}$

Verification:

$\rm{7m + 12 = - 4m + 78}$

⋆ Now, putting the value of x.

$\implies \tt{7 \times 6 + 12 = - 4 \times 6 + 78}$

$\implies \tt{42 + 12 = - 24 + 78}$

$\implies \bf{54 = 54}$

$\therefore \text{Hence, verified}$
