Question

Match the systems of equations with their solutions.
Solution Answers
(-31, -56) x-y= 25, 2x+3y=180
(51, 26) 2x-3y= -5,x+y/11=50
(47, 33) x-y=19,-2x+y/6=28
(-17, -36) 2x-y=-6,x-305/3=2y

Answer 2

I'll try to explain this through example. The first "solution" is (-31,-56). In other words, x=-31 and y=-56. Substitute these x- and y-values into the first equation. Is that equation now true or false? If true, that (-31,-56) is a "solution" of the first equation. If false, it is not, and you'll have to keep going in the same way until you find the equation to which (-31,-56) is a solution.
