Answer 1

Respuesta:

x/2 + 20 = 80

x/2 = 80 - 20

x/2 = 60

x = 60 • 2

x = 120

n/6 + 36 = 72

n/6 = 72 - 36

n/6 = 36

n = 36 • 6

n = 216

2x/3 + 24 = 42

2x/3 = 42 - 24

2x/3 = 18

2x = 18 • 3

x = 54 ÷ 2

x = 27

5x/2 - 20 = 60

5x/2 = 60 + 20

5x/2 = 80

5x = 80 • 2

5x = 160

x = 160 ÷ 5

x = 32

2x/3 + 3/2 = 29/6

2x/3 = 29/6 - 3/2

2x/3 = 10/3

2x = 10/3 • 3

2x = 10

x = 10 ÷ 2

x = 5

3y/8 + 2y/3 = 25

25y/24 = 25

25y = 25 • 24

25y = 600

y = 600 ÷ 25

y = 24

x/3 + x/2 + x/4 − x/6 = 66

11x/12 = 66

11x = 66 • 12

11x = 729

x = 729 ÷ 11

x = 72

6m/4 − 2m/3 − m/2 = 12

3m/2 - 2m/3 - m/2 = 12

m/3 = 12

m = 12 • 3

m = 36

3x/10 − 4x/15 = 1/6

x/30 = 1/6

x = 1/6 • 30

x = 30 ÷ 6

x = 5
