x=4 y=12, . Show how you built the equations using your integers.

Question

1. Select any two integers between -12 and +12 which will become solutions to a system of two equations.
2. Write two equations that have your two integers as solutions. Show how you built the equations using your integers. Your solution and equations should not be the same as those of other students or the textbook. There are infinite possibilities.

 

Answer 1

x + y = 16
x - y = -8

Step 1) Choose two random numbers between -12 and 12 (4 and 12 in this case).

Step 2) Let one of the numbers be x and the other be y.

Step 3) Add both numbers together to form 1 equation.

Step 4) Subtract one number from another to form the other equation.

And with that, we are done.
