Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y)2.

2x-6 < 5+7x 2x-7x < 5+6 -5x < 11 x > -2.5
What is 2x 4 X 7x-1?
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1
2x + 18 = 7x - 30?
2x+18=7x-30 7x-30=2x=18 7x-2x=18+30 5x=48 x=9.6
