How do I solve x-y=11 2x+y=19

Sagot :

x-y=11 2x+y=19
x=11+y
2(11+y)+y=19
22+2y+y=19
3y=-3
y=-1
x=11-1=10

Answer: X = 10 and Y = -1

Step-by-step explanation:

X - Y = 11

X = 11 + Y (plug into the other equation)

2X + Y = 19

2 ( 11+Y ) + Y = 19

22 + 2Y + Y = 19

22 + 3Y = 19

-22 -22

————————-

3Y = -3

Y = -1 (plug into the original formula)

X - Y = 11

X - (-1) = 11

X + 1 = 11

-1 -1

—————

X = 10
