3x-2 and 2x-9, now for this it kind of depends on how the equation is set out if it set out likw this 3x-2+2x-9 then you would answer it like this: -6x+-18x= 12x
3(x plus 2) expanded --> 3x+6 Check out wolframalpha.com for more explanation (not advertising)
Oh, isn't that just lovely? To expand x(3x + 2), you simply distribute the x to both terms inside the parentheses. So, you would have 3x^2 + 2x. Just like painting happy little trees, math can be a beautiful and calming experience when you take it step by step.
3x + 2 = 3x + 6 This is not possible.
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5
