Solve this system of equations algebraically using substitution y= x + 4 and x + y=2

Mathematics
1 answer:
barxatty [35]3 years ago

Answer:

x = -1, y = 3

Step-by-step explanation:

To solve this system of equations, you have to plug in the value of y from the first equation into the second equation:

x + (x + 4) = y

2x + 4 = 2

2x = -2

x = -1

Then, plug x = -1 into one of the equations:

y = (-1) + 4

y = 3
