Question

question is =>>
a-4/7 -a = 5-a/3 +1​

Answer 1

Answer:

$\frac{ - 68}{11}$

Step-by-step explanation:

$\frac{a - 4}{7} - a = \frac{5 - a}{3} + 1 \\ \frac{ - 6a - 4}{7} = \frac{8 - a}{3} \\ - 18a - 12 = 56 - 7a \\ - 11a = 68 \\ a = \frac{ - 68}{11}$

Answer 2

Step-by-step explanation:

a - 4/7 - a = 5-a/3 + 1

-4 - 6a/7 = 8- a/3

Now cross multiplication

3(-4-6a) = 7(8 - a)

-12 - 18a = 56 - 7a

-11a = 68

a = - 68/11
