Answer:

x = 4 -- Marcus

y = 11 -- Raquel

Step-by-step explanation:

Given

x =Marcus

y = Raquel

x + y = 15 -- Both

y = 2x + 3 -- Raquel

Required

Determine x and y

Substitute 2x + 3 for y in x + y = 15

x + 2x + 3 = 15

3x + 3 = 15

Collect Like Terms

3x = 15-3

3x = 12

Divide both sides by 3

x = 4

Substitute 4 for x in

y = 2x + 3

y = 2 * 4 + 3

y = 8 + 3

y = 11
