3x=5y%2B2
to find the ordered pairs that are both solutions of the given equation, you can simply plug in given values for x and y and check for which pair equation is true:
A)(5,3) and (4 ,2)
3x=5y%2B2=>3%2A5=5%2A3%2B2=>15%3C%3E17 ..... not solution, and we don't need to check (4 ,2) because we need pairs that are both solutions
B)(0,-1) and (-6,-4)
3x=5y%2B2=>3%2A0+=5%2A%28-1%29%2B2=>0%3C%3E-3........ not solution
C)(1,1/5)and (4,2)
3x=5y%2B2=>3%2A1+=cross%285%29%2A%281%2Fcross%285%29%29%2B2=>3=1%2B2=>3=3........ this pair IS a solution
3x=5y%2B2=>3%2A4+=5%2A2%2B2=>12=10%2B2=>12=12........ this pair IS a solution
so, C is your answer
D)(0,1) and (-6,4)
