Question

a) 4x + 10 = 22
x = 2
x = 3
x = 4
x = 5
b) 3x – 1 = 5 *
x = 2
x = 3
x = 4
x = 5
c) 6x – 3 = 2x + 17 *
x = 2
x = 3
x = 4
x = 5
d) 4x + 5 = 2x + 13 *
x = 2
x = 3
x = 4
x = 5

Answer 1

4x=22-10

4x= 12

x= 12/4

x=3

3x – 1 = 5

3x= 5+1

3x= 6

x=6/3

×=2

6x – 3 = 2x + 17

6x-2x= 17+3

4x=20

x=20/4

x=5

4x + 5 = 2x + 13

4x-2x= 13-5

2x=8

x=8/2

x=4
