Answer:
x = 4 y= -1
Step-by-step explanation:
Solve the system by elimination by stacking the equations lining up the variables.
2x + 7y = 1
2x - 4y = 12
Next, subtract each of the like terms.
2x + 7y = 1
- 2x - 4y = 12
-----------------------
0x +11y = -11
y = -1
Then substitute y = -1 into one of the equations.
2x + 7(-1) = 1
2x - 7 = 1
2x = 8
]x = 4
