What are your choices? There are a lot of solutions

OpenStudy (anonymous):

how do you work it out and get the answer the choices are (8,10),(-2,4),(3,-3), or (-7,11)

OpenStudy (anonymous):

(3,3);(-2,-4);(8,10);(13,17);(18,24);(23,31) these are all solutions

OpenStudy (anonymous):

so it is (8,10) just plug in 8 for x and plug in 10 for y 7(8)-5(10)=6 56-50=6 6=6

OpenStudy (anonymous):

can you show me how u got (8,10)

OpenStudy (anonymous):

Since you have 4 choices, just plug each into the equation to check. If it equals 6, then that is a solution.
