Answer:
y = 5 and x = 2
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
