b) 3x-4=2x+8
c) 7x-28=2x+7
d)4x-1=3x-3
e)6x+10=3x-5
f)18x-100=8x+200
g)8x-3=5x+21
h)7x-21=3x+7
​

Answer 1

a) 5x+7=4x+10

5x - 4x = 10 - 7

x = 3

b) 3x-4=2x+8

3x - 2x = 8 + 4

x = 12

c) 7x-28=2x+7

7x - 2x = 7 + 28

5x = 35

x = 35/5

x = 7

d)4x-1=3x-3

4x - 3x = -3 + 1

x = -2

e)6x+10=3x-5

6x - 3x = -5 - 10

3x = -15

x = -15/3

x = -5

f)18x-100=8x+200

18x - 8x = 200 + 100

10x = 300

x= 300/10

x= 30

g)8x-3=5x+21

8x - 5x = 21 - 3

3x = 18

x = 18/3

x = 5

h)7x-21=3x+7

7x - 3x = 7 + 21

4x = 28

x = 28/4

x= 7
