Verified answer

4a)
6x + 5 = 26 - x
6x + x = 26 - 5
7x = 21
x = 21/7
x = 3

b)
2 - 4x = 3
-4x = 3 - 2
-4x = 1
x = -1/4

c)
x - 12 = 2x + 36
x - 2x = 36 + 12
-x = 48
x = 48/-1
x = -48

d)
-5x - 4x + 10 = 1
-9x + 10 = 1
-9x = 1 - 10
-9x = -9
x = -9/-9
x = 1

e)
2 + x/4 = 5
x/4 = 5 - 2
x/4 = 3
x = 3 × 4
x = 12

5)
3x + 12 = 7x - 8
3x - 7x = -8 - 12
-4x = -20
x = -20/-4
x = 5

x + 2
= 5 + 2
= 7

6)
3x - 4 = 2x + 1
3x - 4 - 2x = 2x + 1 - 2x
x - 4 = 1
x - 4 + 4 = 1 + 4
x = 5
