Consider this system of equations, which has one solution
2x+2y=181
0.1x+7y=78
here are some equivalent systems. each one is a step in solving the original system.
step 1:
7x+7y=630
0.1x+7y=78
step2:
6.9x=552
0.1x+7y=78
step 3
x=80
0.1x+7y=78
question 1: what was done to the original system to get the system in step 1?
look at the system in step 1 and the system in step 2
question 2: what was done to the system in step 1 to get the system in step 2?
explain why the system in step 2 shares a solution with that in step 1?
what is the solution to the original system?
nice work who answer this first
