a) 9x-8 = 11x-10
9x - 11x = -10 + 8
-2x = -2
x = 2/2
x = 1
b) 1-2x-(3x-10) = 7(3-x)
1-2x-3x+10 = 21-7x
-2x-3x+7x = 21 -1-10
2x = 10
x = 10/2
x = 5
c)38/2 +5 = 5x/2 - 1
19+5=5x/2 -1
24 = 5x/2-1
48 = 5x - 2
-5x = -50
x = 50/5
x = 10
d) x/4+8 = x/3 + 8
3x + 96 = 4x + 96
3x - 4x = 96 -96
-x = 0
x = 0
9x - 11x = -10 + 8
-2x = -2
x = 2/2
x = 1
b) 1-2x-(3x-10) = 7(3-x)
1-2x-3x+10 = 21-7x
-2x-3x+7x = 21 -1-10
2x = 10
x = 10/2
x = 5
c)38/2 +5 = 5x/2 - 1
19+5=5x/2 -1
24 = 5x/2-1
