Simplist form of 2x plus 3-10 is 2x-7.
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.
5x-6+23-7x 5x-7x+23-6 (rearranged) -2x+17 (simplification).
8x-4
3x + 2x - 8x + 2x = -x
There is no simplification. It is sqrt(6X +4)There is no simplification. It is sqrt(6X +4)There is no simplification. It is sqrt(6X +4)There is no simplification. It is sqrt(6X +4)
x=1
It is 2x+(-2x) = 0
