Which ordered pair is a solution to the system of linear equations?
2 answers:
(0,2)............................................
We have to add the equations in a clever way such that one of the variables cancels out. If you multiply the top one with 3 and the bottom one with 2, you cancel x. Like this: 3(2x+3y)=3*6 => 6x + 9y = 18 2(-3x+5y)=2*10 => -6x + 10y = 20 9y + 10y = 38 => 19y = 38 => y=2 If y=2 then 2x + 6 = 6 => x=0 The pair (0,2) is a solution.

The square root and the squared cancel each other out so it would just be 27 to the first power,which is 27
