Respuesta :
x + y = 19
x - y = -7
Subtract both
2y = 26, y = 13
Plug into first equation
x + 13 = 19
x = 6
Solution: x = 6, y = 13
x - y = -7
Subtract both
2y = 26, y = 13
Plug into first equation
x + 13 = 19
x = 6
Solution: x = 6, y = 13
Answer:
x = 6
y = 13
Step-by-step explanation:
x + y = 19
x - y = -7
To eliminate x, subtract ther second equation from the first
2y = 26
y = 13
To eliminate y, add the equations
2x = 12
x = 6
