Answer 1

Simplifying

2x + 4y = 9

Solving

2x + 4y = 9

Solving for variable 'x'.

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

Add '-4y' to each side of the equation.

2x + 4y + -4y = 9 + -4y

Combine like terms: 4y + -4y = 0

2x + 0 = 9 + -4y

2x = 9 + -4y

Divide each side by '2'.

x = 4.5 + -2y

Simplifying

x = 4.5 + -2y
