Y=-7x+3

y=-x-3



what is x

what is y

x = 1, y = - 4

Step-by-step explanation:

Given the 2 equations

y = - 7x + 3 → (1)

y = - x - 3 → (2)

Substitute y = - x - 3 into (1)

- x - 3 = - 7x + 3 (add 7x to both sides)

6x - 3 = 3 (add 3 to both sides)

6x = 6 (divide both sides by 6)

x = 1

Substitute x = 1 into either of the 2 equations for value of y

Substituting in (2)

y = - 1 - 3 = - 4
