Question

A) 6x = 2x + 16
B) 2x - 5 = x + 1
C) 2x + 3 = x + 4
D) 5x + 7 = 4x + 10
E) 5x - 3 + x = 2x + 9
F)17x - 7x = x + 18
G) x + x - 4 = 17 - 2x + 1

Answer 1

A) 6x = 2x + 16

6x-2x=16

4x=16

x=4

B) 2x - 5 = x + 1

2x-x=1+5

x=6

C) 2x + 3 = x + 4

2x-x=4-3

x=1

D) 5x + 7 = 4x + 10

5x-4x=10-7

x=3

E) 5x-3 + x = 2x +9

6x3 2x +9

6x-2x = 9+3

4x = 12

x=3

F) 17x-7x= x + 18

10x = x + 18

10x - x = 18

9x = 18

x = 2

G) x + x-4 =17 - 2x + 1

2x-4=18-2x

2x + 2x = 18 +4

4x = 22

11

x= ––

2
