For some value of x , 5(x+2) =y . After the value of x is increased by ,3 5(x+2) =z. what is the value of (z -y) ?

For some value of x , 5(x+2) =y . After the value of x is increased by ,3 5(x+2) =z. what is the value of (z -y) ? Correct Answer 15

Here, y = 5(x + 2) z = 5(x + 3 + 2) [using x + 3 in place of x] Now, z - y = 5(x + 5) - 5(x + 2) = 5x + 25 - 5x - 10 = 15
