Yes; that's because the powers of the variables are the same .. -7x has a variable x with power 1 (x^1), and so is 4x.
4x and -7x are like terms because they are both multiplying x. It While (4 +- 7)x = -3x

no,, to be like term they must have the same variable,, such as 4x and 9x.. or 1y and 300y...
12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
You move one of the like terms to the other side using algebraic operations. For instance... 3x + 5y = 7x + 3 ... and you want to solve for x ... ... first, subtract 3x from both sides ... 3x - 3x + 5y = 7x - 3x + 3 5y = 4x + 3 ... do I need to explain further???
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
