x+2y =25
Solving
x + 2y = 25
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
x + 2y + -2y = 25 + -2y
Combine like terms: 2y + -2y = 0
x + 0 = 25 + -2y
x = 25 + -2y
Simplified
x = 25 + -2y
x-y = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
x + -1y + y = 11 + y
Combine like terms: -1y + y = 0
x + 0 = 11 + y
x = 11 + y
Simplifying
x = 11 + y
