3x + y = -8
My answer: y=-11
2x - y = 11
My Answer: y=13
3x + y = -8
y = -8 -3x
2x - y = 11
y= 2x - 11
Thank you so much! How did you get those though? I cant seem to figure it out...
Let's check the given answers to the equations:
Equation 1: 3x + y = -8
To solve for y, we can isolate it by moving the 3x term to the other side of the equation:
3x + y = -8
Subtract 3x from both sides:
y = -8 - 3x
So, the correct equation for y is y = -8 - 3x. Therefore, your answer of y = -11 is incorrect.
Equation 2: 2x - y = 11
To solve for y, we can isolate it by moving the 2x term to the other side of the equation:
2x - y = 11
Add y to both sides:
2x = 11 + y
Subtract 11 from both sides:
2x - 11 = y
So, the correct equation for y is y = 2x - 11. Therefore, your answer of y = 13 is incorrect.
To find the correct answers for y, you need to rearrange the equations as shown above.
