Question

m-m-2/7=4-m-3/6 solve and verify
​

Answer 1

Step-by-step explanation:

m-m-

$m - m - \frac{2}{7} = 4 - m - \frac{3}{6}$

$2m - \frac{2}{7} = 4 - m - \frac{3}{6}$

Now,

take similar variables on one side

$2m + m = 4 - \frac{3}{6} + \frac{2}{7}$

now solve it ,

take lcm of 3/6 & 2/7

$3m = 4 - \frac{3 \times 7}{6 \times 7} + \frac{2 \times 6}{7 \times 6}$

$3m =4 - \frac{21}{42} + \frac{12}{42}$

$3m = 4 - \frac{21 + 12}{42} \\ \\ 3m = 4 - \frac{33}{42} \\ \\ 3m = \frac{42 \times 4 - 33}{42 } \\ \\ \\ \\ 3m = \frac{168 - 33}{42} \\ \\ 3m = \frac{135}{42} \\ 3m \times 42 = 135 \\ \\ 126m = 135 \\ \\ m = \frac{135}{126} \\ \\ m = \frac{15}{14} \\ = 1.6$
