Answer:

(0, 3 )

Step-by-step explanation:

Given the 2 equations

x + 3y = 9 → (1)

- 2x + 2y = 6 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the x- term

2x + 6y = 18 → (3)

Add (2) and (3) term by term to eliminate x, that is

0 + 8y = 24

8y = 24 ( divide both sides by 8 )

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x + 3(3) = 9

x + 9 = 9 ( subtract 9 from both sides )

x = 0

solution is (0, 3 )

Answer this question
Murljashka [212]

Answer:

a = p * q

b = p * s + q * r

c = r * s

Step-by-step explanation:

In the trinomial ax² + bx + c

a is the coefficient of x²

b is the coefficient of x

c is the numerical term

∵ The trinomial is ax² + bx + c

∵ Its factors are (px + r) and (qx + s)

∴ ax² + bx + c = (px + r)(qx + s)

∵ (px + r)(qx + s) = (px)(qx) + (px)(s) + r(qx) + (r)(s)

∴ (px + r)(qx + s) = pqx² + (psx + qrx) + rs

∴ ax² + bx + c = pqx² + (ps + qr)x + rs

→ By comparing the two sides

∵ ax² = pqx² ⇒ divide both sides by x²

∴ a = pq

∵ bx = (ps + qr)x ⇒ Divide both sides by x

∴ b = ps + qr

∴ c = rs

∴ a = p * q

∴ b = p * s + q * r

∴ c = r * s
