Question

X is equal to 8 times y and the respective ratio between (x + 20) and 2y is 37 : 8. What is the value of x ?

Answer 1

Answer:

128

Step-by-step explanation:

x = 8y   ----------- [1]

x + 20 / 2y = 37/8  --------------- [2]

4x + 80/8y = 37/8

4x + 80/x = 37/8

32x + 640 = 37x

5x = 640

x = 128.
