Answer:
There is one solution (0, 2)
Step-by-step explanation:
Let us solve the question
∵ y = x + 2 ⇒ (1)
∵ 2y = x + 4 ⇒ (2)
→ Substitute y in equation (2) by equation (1)
∴ 2(x + 2) = x + 4
∵ 2(x) + 2(2) = x + 4
∴ 2x + 4 = x + 4
→ Subtract x from both sides
∵ 2x - x + 4 = x - x + 4
∴ x + 4 = 4
→ Subtract 4 from both sides
∵ x + 4 - 4 = 4 - 4
∴ x = 0
→ Substitute the value of x in equation (1) to find y
∵ y = 0 + 2
∴ y = 2
∴ There is one solution (0, 2)
