1. 22-3x+7x=4(x+5)
OpenStudy (anonymous):
2. 6(2x-3)=3(3x-5)
OpenStudy (anonymous):
22 - 3x + 7x = 4(x + 5)
22 + 4x = 4(x + 5)
22 + 4x = 4x + 20
22 - 20 + 4x = 4x + 20 - 20
2 + 4x - 4x = 4x - 4x
2 = 0

4. 6x+3(x-4)=8(x-3)
OpenStudy (anonymous):
6(2x-3)=3(3x-5)
12x - 18 = 3(3x - 5)
12x - 18 = 9x - 15
12x - 18 + 18 = 9x -15 + 18
12x - 9x = 9x - 9x + 3
3x = 3
x = 1
OpenStudy (anonymous):
6x-14=2(3x-7)
6x - 14 = 6x - 14
OpenStudy (anonymous):
6x+3(x-4)=8(x-3)
6x + 3x - 12 = 8x - 24
9x - 12 = 8x - 24
9x - 12 + 24 = 8x - 24 + 24
9x + 12 = 8x
9x - 9x + 12 = 8x - 9x
12 = -x
-12 = x
