Step-by-step explanation:

a. 12 + 4 = 16

1st left equation is matched to 4th right value

b. 3(4) + 7 = 19

2nd left equation is correctly matched to 2nd right value

c. 4(7) - 10 = 18

3rd left equation is matched to 1st right value

d. 1 / 2 × xy

1 / 2 × (4 × 7)

= 28 ÷ 2

= 14

4th left equation is matched to 3rd right value
