<span>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 :)</span>

-- 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.

(If this is really high school, then you're supposed to know this by now.)

Can someone please help me with this problem
Nadusha1986 [10]
X= 2/3

6x/x-6 - 4/x - 24 / x^2 - 6x = 0


6x^2 -4 (x-6)-24 / x(x-6) = 0

6x^2 -4x+ 24 -24/x(x-6) = 0

X(6x-4) / x(x-6)

6x-4/x-5 = 0

6x-4= 0

6x = 4 divide both sides by 6
X= 2/3
