Question

A) 3x -2 = 5 x - 6
B) 2x + 3 = 19
C) 6 x + 3 = 19 + x + 4
D) 3 x - 2 = 2 x - 109
E) 6 x - 3 = 3 x + 2
F) 3 x - 6 = 9
G) 12 + 13 - x = 4 x - 3
H) 12 + 11 + 10 x =32 + 9
I) 6 x - 7 x + 8 = 3+ 4 x
J) 12 x - 3 x + 4 + 6 - 9 = 0

Answer 1

a) 3x -5x = -6 +2

-2x = -4

x = -4/-2

x = +2

b) 2x = 19-3

2x = 16

x = 16/2

x= 8

c) 6x - x = 19 +4 -3

5x = 20

x = 20/5

x = 4

d) 3x - 2x = - 109 +2

x = - 107

e) 6x -3x = 2+3

3x = 5

x = 5/3

f) 3x = 9+6

3x = 15

x = 15/3

x = 5

g) 25 - x = 4x -3

- x -4x = -3 -25

- 5x = -28

x = -28/-5

x = +28/5

h) 23 +10x = 41

10x = 41 -23

10x = 18

x = 18/10

x = 9/5

i) - x +8 = 3 +4x

- x - 4x = 3 -8

- 5x = -5

x = -5/-5

x = +1

j) 9x +10 -9=0

9x +1=0

9x = - 1

x = -1/9
