what is the solution to the system containing the equation ? x + y = 8 and 3x + 2y = 9

Algebra 
PsyDAG,
Multiply first equation by 3.
3x + 3y = 24
3x + 2y = 9
Add the two equations.
5y = 15
y = 3
Put y value in one equation.
x + (3) = 8
x = 5
Check by putting both values in the other equation.
(3)(5) + 2(3) = 9
156 = 9
