X+2y=4
+-x-4y=-14
——————
-2y=-10, y=5, x=4-10=-6
Answer:
x = -6
y = 5
Step-by-step explanation:
Add the equations
1x + 2y = 4
-1x - 4y = -14
————————
-2y = -10
Divide both sides by -2
y = 5
Substitute for y = 5 into either equation
using 1x + 2y = 4
1x + 2(5) = 4
1x + 10 = 4
Subtract 10 from both sides
1x = -6
x = -6
Solution
x = -6
y = 5
