Question

2 x -4 = 8

5a + 5 = 20

m + 8 = 10

10 + 8x = 50

x + 8 + 3 x = 24

y - 12 = 8

3k - 2 = 25

3x + 8 - x= 10

3a - 12 + a = 12​

Answer 1

2x-4=8

2x-4+4=8+4

2x=12

2x/2 = 12/2

x=6

5a+5=20

5a+5-5=20-5

5a=15

5a/5 = 15/5

a=3

m+8=10

m+8-8=10-8

m=2

10+8x=50

10+8x-10=50-10

8x=40

8x/8 = 40/8

x=5

x+8+3x=24

x+3x+8=24

4x+8=24

4x+8-8=24-8

4x=16

4x/4 = 16/4

x=4

y-12=8

y-12+12=8+12

y=20

3k-2=25

3k-2+2=25+2

3k=27

3k/3 = 27/3

k=9

3x+8-x=10

3x-x+8=10

2x+8=10

2x+8-8=10-8

2x=2

2x/2 = 2/2

x=1

3a-12+a=12

3a+a-12=12

4a-12=12

4a-12+12=12+12

4a=24

4a/4 = 24/4

a=6

Answer 2

2x -4 = 8
2x = 8 + 4
2x = 12
x = 12/2
x = 6

—————————————————————

5a + 5 = 20
5a = 20 - 5
5a = 15
a = 15/5
a = 3

—————————————————————

m + 8 = 10
m = 10 - 8
m = 2

—————————————————————

10 + 8x = 10
8x = 10 - 10
8x = 0
x = 0/8
x = 0

—————————————————————

x + 8 + 3x = 24
x + 3x = 24 - 8
4x = 16
x = 16/4
x = 4
