Answer:

cost of 1 muffin is £1 , cost of cake is £3

Explanation:

setting up the simultaneous equations

2x + y = 5 → (1)

5x + y = 8 → (2)

subtract (1) from (2) term by term to eliminate y

(5x - 2x) + (y - y) = 8 - 5

3x + 0 = 3

3x = 3 ( divide both sides by 3 )

x = 1

substitute x = 1 into either of the 2 equations and solve for y

substituting into (1)

2(1) + y = 5

2 + y = 5 ( subtract 2 from both sides )

y = 3

the cost of a muffin is £1 and the cost of a cake is £3
