Answer: x = -3 y = 2 So (-3,2)
Explanation:
- x + 3y = 9 Multiply everything by 2 then add to the second equation.
2x + 5y = 4
-2x +6y =18 then 2x-2x=0 Add the other terms and solve for y.
11y = 22 divide both sides by 11 yo get y = 2 Substitute that into either one and solve for x.
2x + 5y = 4
2x + 5(2) = 4
2x + 10 = 4 subtract 10 from both sides 2x = 4 -10
2x = -6 so divide both sides by 2 to get x = -3
