Question

a)-x+3=x-3
b)5x+3+4x=-9+3x-5
c)2x-3x=5x+1
d)4x+2=9-5

Answer 1

A) - x + 3 = x - 3
- x - x = - 3 - 3
- 2x = - 6
x = - 6 / - 2
x = 3

B) 5x + 3 + 4x = - 9 + 3x - 5
5x + 4x - 3x = - 9 - 5 - 3
9x - 3x = - 14 - 3
6x = - 17
x = - 17/6

C) 2x - 3x = 5x + 1
2x - 3x - 5x = 1
- x - 5x = 1
- 6x = 1 (-1)
6x = - 1
x = - 1/6

D) 4x + 2 = 9 - 5
4x = 9 - 5 - 2
4x = 4 - 2
4x = 2
x = 2/4 (÷2)
x = 1/2
