Answer:
x < -3
Step-by-step explanation:
First subtract 6 from both sides of the inequality.


Divide 4 on both sides.


(2x+3y)+(7x-3y)
First, group like terms together, so (2x+7x) + (3y-3y). Then simplify within the parentheses. 2x+7x = 9x and 3y-3y = 0, so you have 9x, which cannot be simplified any further. The answer is 9x.
