Answer 2

Answer:

y = 5 and x = 2

Step-by-step explanation:

Since we have x = -3y + 17, we're going to substitute this equation into the x-value in the second equation.

2(-3y + 17) - y = -1

Multiply the 2 with the terms within the parentheses.

-6y + 34 - y = -1

Add the y values.

-7y + 34 = -1

Subtract 34 from both sides.

-7y = 35

Divide each side by -7.

y = 5

Now that we know the value of y, we can substitute 5 for the y-value in the first equation.

x = -3(5) + 17

Multiply.

x = -15 + 17

Add the two terms together.

x = 2
