Answer:
Simplifying
5x + 4y = 9
Solving
5x + 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.
5x + 4y + -4y = 9 + -4y
Combine like terms: 4y + -4y = 0
5x + 0 = 9 + -4y
5x = 9 + -4y
Divide each side by '5'.
x = 1.8 + -0.8y
Simplifying
x = 1.8 + -0.8y
Hope this helps ^^
