Answer:
(2,5)
or x=2, y=5
Step-by-step explanation:
3x+2y=16
substitute y =x+3 every place you see a y
3x + 2(x+3) = 16
distribute
3x + 2x +6 = 16
combine like terms
5x+6 = 16
subtract 6 from each side
5x+6 -6 =16-6
5x =10
divide by 5
5x/5 = 10/5
x = 2
now we need to find y
y = x+3
y = 2+3
y=5
(2,5)
or x=2, y=5
