Which of the following is equivalent to the expression below? ( 6 x − 4 y + 9 ) + ( − 3 x − 2 y )

3x - 6y + 9

Step-by-step explanation:

Given

(6x - 4y + 9) + (- 3x - 2y)

Since both parenthesis are distributed by 1, just remove them, that is

= 6x - 4y + 9 - 3x - 2y  ← collect like terms

= (6x - 3x) + (- 4y - 2y) + 9

= 3x - 6y + 9

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation
