Answer:
y = 3
Step-by-step explanation:
Given an equation such that,
(3+y)/(y+7) = 3/5
To solve the equation.
On cross multiplication, we get,
=> 5(3+y) = 3(y+7)
=> 15 + 5y = 3y + 21
=> 5y - 3y = 21 - 15
=> 2y = 6
=> y = 6/2
=> y = 3
Verification:
L.H.S
= (3+y)/(y+7)
= (3+3)/(3+7)
= 6/10
= 3/5
= R.H.S
°.° L.H.S = R.H.S
Thus, verified.
Hence, required value of y = 3.
