Answer:
{x,y} = {2,9}
Step-by-step explanation:
Solve equation [2] for the variable y
[2] 2y = -6x + 30
[2] y = -3x + 15
// Plug this in for variable y in equation [1]
[1] 3x + 2•(-3x+15) = 24
[1] -3x = -6
// Solve equation [1] for the variable x
[1] 3x = 6
[1] x = 2
// By now we know this much :
x = 2
y = -3x+15
// Use the x value to solve for y
y = -3(2)+15 = 9
