Answer 2

Answer:

x = - 5 , y = 0

Step-by-step explanation:

- 4x + 7y = 20 → (1)

y = 3x + 15 → (2)

Substitute y = 3x + 15 into (1)

- 4x + 7(3x + 15) = 20 ← distribute parenthesis and simplify left side

- 4x + 21x + 105 = 20

17x + 105 = 20 ( subtract 105 from both sides )

17x = - 85 ( divide both sides by 17 )

x = - 5

Substitute x = - 5 into (2)

y = 3(- 5) + 15 = - 15 + 15 = 0

Then x = - 5 , y = 0 is the solution to the system
