5 -3(4-2x) + 3 -2(5-x) = 5 - 12 + 6x + 3 - 10 + 2x = 8x - 14
8(x-4) + 9 -3(x+5) + 38 = 0
8x - 32 + 9 - 3x - 15 + 38 = 0
5x = 0/÷5
x = 0
2 = 4x - 3 + 5x - 8 - 6x - 3
2 = 3x - 14
-3x = -14 - 2
-3x = -16/÷(-3)
x = 16/3
5x + 3x - 2x = 5 - 2 + 4x
6x - 4x = 3
2x = 3/÷2
x = 3/2
3 - 2x = 1 -(-2+x)
3 - 2x = 1 + 2 - x
-x = 0/÷(-1)
x = 0
6 + 4(3-k) = 3(-2k+9)
6 + 12 - 4k = -6k + 27
2k = 9/÷2
k = 9/2
