Question

3+y / y+7 = 3/5
check the answer too​

Answer 1

Answer:

"We have, (2-y) / (y+7) = 3/5

Let us perform cross-multiplication we get,

5(2-y) = 3(y+7) 10 – 5y = 3y + 21

When rearranged,

10 – 21 = 3y + 5y 8y = – 11 y = -11/8

Now let us verify the given equation,

(2-y) / (y+7) = 3/5

By substituting the value of ‘x’ we get,

(2 – (-11/8)) / ((-11/8) + 7) = 3/5

((16+11)/8) / ((-11+56)/8) = 3/5

(27/8) / (45/8) = 3/5 (27/8) × (8/45) = 3/5

27/45 = 3/5 3/5 = 3/5

Hence, the given equation is verified. "
