Answer 1

Respuesta:

Simplifying

90 = 2x + y

Solving

90 = 2x + y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

90 + -2x = 2x + -2x + y

Combine like terms: 2x + -2x = 0

90 + -2x = 0 + y

90 + -2x = y

Add '-90' to each side of the equation.

90 + -90 + -2x = -90 + y

Combine like terms: 90 + -90 = 0

0 + -2x = -90 + y

-2x = -90 + y

Divide each side by '-2'.

x = 45 + -0.5y

Simplifying

x = 45 + -0.5y
