Question

a) x + 5 = 6

b) x – 4 = 3

c) 3x = 15

d) x/3 = 7

e) 4 (x + 3) = 20

f) x/2 – x/4 = 1/2
Me ajudem na avaliaçao

Answer 1

a) x + 5 = 6

x = 6 - 5

x = 1

b) x - 4 = 3

x = 3 - 4

x = - 1

c) 3x = 15

x = 15/3

x = 5

d) x/3 = 7

x = 7 × 3

x = 21

e) 4 (x + 3) = 20

4x + 12 = 20

4x = 20 - 12

4x = 8

x = 8/4

x = 2

f) x/2 - x/4 = 1/2

2x - x/4 = 2/4

2x - x = 2

x = 2
