If x is 4 more than half of y and if y is 10 more than half of x, what is the value of x?

enter your value x is 4 more than half of yWe can write:

x = y/2 + 4y is 10 more than half of xWe can write:

y = x/2 + 10Take

x = y/2 + 4 and replace

y with

x/2 + 10 We get: x = (

x/2 + 10)/2 + 4

Multiply both sides by 2 to get: 2x = x/2 + 10 + 8

Multiply both sides by 2 (again) to get: 4x = x + 20 + 16

Subtract x from both sides: 3x = 36

Solve:

x = 12Cheers,
