Use elimination to solve each system of equations.
x+y+3 (I think you mean x + y = 3, here)
2x-3y=16
:
<
multiply the 1st equation by 3 and add to the 2nd equation
3x + 3y = 9
2x - 3y = 16
------------------additions eliminates y, find x
5x = 25
x = 25%2F5
x = 5
:
find y using the 1st equation: x + y = 3
5 + y = 3
y = 3 - 5
y = -2
;
Check it in the 2nd equation 2x - 3y = 16
2(5) - 3(-2) = 16
10 + 6 = 16
