Pleeassseee help me out. 3x - 12y = 60 x + 2y = 14

Answer 1

Answer: y = 5     x = 0

Step-by-step explanation:

Answer 2

Answer:

((16, - 1)

Step-by-step explanation:

Given the 2 equations

3x - 12y = 60 → (1)

x + 2y = 14 → (2)

Rearrange (2) expressing x in terms of y by subtracting 2y from both sides

x = 14 - 2y → (3)

Substitute x = 14 - 2y into (1)

3(14 - 2y) - 12y = 60

42 - 6y - 12y = 60

42 - 18y = 60 ( subtract 42 from both sides )

- 18y = 18 ( divide both sides by - 18 )

y = - 1

Substitute y = - 1 into (3) for corresponding value of x

x = 14 + 2 = 16

Solution is (16, - 1)
