2x + 7b is an expression. Since it is not an equation it cannot be solved. Furthermore, as an expression, there is no meaninful simplification, either.
w + 2x + 3w - 2xw = 2x + 4w - 2xw, in simplest form
y=x+5
2x+y=1
2x + y = 7y = -2x + 7
2x + -94x - 29x-121x

5x-6+23-7x 5x-7x+23-6 (rearranged) -2x+17 (simplification).
w + 2x + 3w - 2xw = 2x + 4w - 2xw, in simplest form
(2x+5)(2x+1)
y=x+5
2x+y=1
2x + y = 7y = -2x + 7
Slope-Intercept Form: y = -2x +1
the simplest form of 5x + 3y +2x - 6y is 7x-3y
2x2 + 5x = x*(2x + 5)
It is: y = 2x-3
