Answer:

1. 18

2. 287

3. 45

Step-by-step explanation:

Use PEMDAS

1. 67 - 8 × 7 + 28 ÷ 4 = n

67 - 56 + 28 ÷ 4

67 - 56 + 7

11 + 7

n= 18

2. ( 45 - 18 ) × 10 + 85 ÷ 5 = n

27 × 10 + 85 ÷ 5

270 + 85 ÷ 5

270 + 17

n = 287

3. 42 + 14 × 3 - ( 26 + 13 ) = n

42 + 14 × 3 - 39

42 + 42 - 39

84 - 39

n = 45
