X-5, y+9
because -5 then positive 5 up
You can solve a system with variables by:
1. Pick any two pairs of equations from the system.
2. Eliminate the same variable from each pair using the Addition/Subtraction method
3. Solve the system of the two new equations using the Addition/Subtraction method
4. Substitute the solution back into one of the original equations and solve for the third variable
5. check by plugging the solution into one of the other three equations
Answer:
42
Step-by-step explanation:
My teacher has asked the class this one before and after a lot of time not knowing she just told us k=42 XD
I believe it’s 82
8x=3x+8+4x+10
x=18
4•18+10=72+10=82
-2.6 I think is the correct answer
