Question

HELPPPPPPPPP AAAAAAAAA​

Answer 1

Answer:

(5, -1)

Step-by-step explanation:

Equation 1:   3x + y = 14

Equation 2:   2x - 2y = 12

Rewrite equation 1 to make y the subject:

⇒ y = 14 - 3x

Substitute this into equation 2 and solve for x:

⇒ 2x - 2(14 - 3x) = 12

⇒ 2x - 28 + 6x = 12

⇒ 8x - 28 = 12

⇒ 8x = 40

⇒ x = 5

Substitute found value for x into either equation and solve for y:

using equation 1:

⇒ 3(5) + y = 14

⇒ 15 + y = 14

⇒ y = -1

Therefore, the solution to the system is (5, -1)
