1.
3x - 1 = 8
3x = 8 + 1
3x = 9 /:3
x = 3
2.
5x - 4 = 4x + 3
5x - 4x = 3 + 4
x = 7
3.
2(2x + 3) = 3 - (x - 2)
4x + 6 = 3 - x + 2
4x + 6 = 5 - x
4x + x = 5 - 6
5x = -1
x = - 1/5
1) 3x - 1 = 8
3x=8+1
3x=9
x=3
2) 5x - 4 = 4x +3
5x-4x=3+4
x=7
3)2(2x + 3) = 3 - (x-2)
4x+6=3-x+2
4x+6=5-x
4x+x=5-6
5x=-1
x= - 1/5
3x=8+1
3x=9
