Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. There is no operator between 5x and 2. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x=10 5x/5=10/5 x=2
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.

4x-7=5x-2 x=-5
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
Here is the work for that problem: 5x+ 2=12 5x= 12-2 5x=10 x= 2
f(x)=5x+2
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x=10 5x/5=10/5 x=2

This cannot be solved. It needs 2 equations to solve for 2 unknowns.
-10.
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
