Answer:
2x³ - 3y + z²
Step-by-step explanation:
-2x³ – y – 2z² + 4x³ – 2y + 3z² Combine like terms
-2x³ + 4x³ – y – 2y – 2z² + 3z²
2x³ - 3y + z²
You have 9n and -7 in total so the answer is 9n-7. You add up all the numbers and then add up the numbers with n attached to them
There wouldn't be a solution: because both equations have the same slope of 3, they would be parallel to each other. The best graph to pick would be the one with two positive steep slopes that are 3 up every one to the right.
I think they intersect t the point 2,-2
So from there you can work out the value of x
