Question 88315: please help me,
show whether or not(5,3) is a solution of the system:
3x+2y=21
x+y=8
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
Just substitute the values for x and y: (5,3) means that x=5 and y =3.
3x+2y=21
3(5) + 2(3) = 21
15 + 6= 21 True
x+y=8
5+3 = 8 True
Yes, it is a solution.
