Simplifying
5x + 2y = 9
Solving
5x + 2y = 9
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.
5x + 2y + -2y = 9 + -2y
Combine like terms: 2y + -2y = 0
5x + 0 = 9 + -2y
5x = 9 + -2y
Divide each side by '5'.
x = 1.8 + -0.4y
Simplifying
x = 1.8 + -0.4y Hope i helped :)
-- Take each choice.
-- Write the first number in place of 'x'.
Write the second number in place of 'y'.
-- If the equation is true, then the choice is a solution of the equation.
