a)2x-1=-3x+10
b)-2x+3=-1+x+2

Answer 1

a) $2x-1=-3x+10$

$2x+3x=1+10$

$5x=11$

$x=\dfrac{11}{5}$

b) $-2x+3=-1+x+2$

$-2x-x=-1+2-3$

$-3x=-2$

$x=\dfrac{-2}{-3}=\dfrac{2}{3}$

Answer 2

a)  2x - 1 = - 3x + 10
2x + 3x = 10 + 1
5x = 11
x = 11/5

b) - 2x + 3 = - 1 + x + 2
- 2x - x = 2 - 1 - 3
- 3x = - 2 (-1)
3x = 2
x = 2/3
