2x-3x+1 can be simplified (by combining like terms, or terms with the same number/type of variables) to -x+1. This is not an equation, but an "expression," meaning that there is no equals sign, and you cannot solve for x without an equals sign. If, for instance, that entire expression was equal to 7,
-x+1=7
-x = 6
x = -6

sixteen m squared plus eight m plus 1
When simplified it is: 1-8x
2y + 7x + y-1?
That factors to (a + 1)(a + b) a = -1, -b b = -a

-1 plus 1 = 0 plus 1 =1
sixteen m squared plus eight m plus 1
x+2x3x
1 + 1 = 2The process used to solve it is "addition."
you add the together and get 46
When simplified it is: 1-8x
2y + 7x + y-1?
2x3x-4= -24
a+a=1 2a=1 a=1/2
That factors to (a + 1)(a + b) a = -1, -b b = -a
This is an expression and you do not solve an expression, but you can factor this one.X2 + 3X4X2(1 + 3X2)========
