How to get y by itself in the equation x+2y=10

The value of y by itself in the equation x+2y=10 is

Step-by-step explanation:

Given equation is x+2y=10  -------- (1)

To find y with given equation as below :

Equation (1) implies that x+2y=10

Subtracting the above equation by x we get

x+2y-x=10-x

x-x+2y=10-x

2y=10-x

Dividing by 2 on both sides we get

Therefore the value of y is

Therefore the value of y by itself in the equation x+2y=10 is
