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
