Question 485322: Select any two integers between -12 & +12, which will become solutions to a system of two equations. Write two equations that have two integers as solutions. Solve your system of equations, using the addition and subtraction method, showing all 5 steps. I chose 5, and -10 as my integers, so
x=5, and y=-10. My equations were:
2x + y = 0
-x + 2y =
-5 + -20 = -25
2x + y = 0
-2x + 4y =
-10 +-40 = -50
5y = -50
y = -10
Then to solve for x,
2x + y = 0
2(5)+ -10 = 0
2x =10
x= 5
Have I done this right, and included all the necessary steps as required?
Please help and show me. Thank you
