Vesna [10]

Answer:

PE = 83 and Science = 71

Step-by-step explanation:

let P represent PE and S represent Science with P > S, then

P + S = 154 → (1)

P - S = 12 → (2)

Adding the 2 equations term by term eliminates S

2P = 166 ( divide both sides by 2 )

P = 83

Substitute P = 83 into (1)

83 + S = 154 ( subtract 83 from both sides )

S = 71

Hence PE mark = 83 and Science mark = 71
