x+2y = -4

Question

4x 8 = -16
Solve and how many solutions

Answer 1

To solve this system of equations, we can use the substitution method.

From the first equation:
x + 2y = -4
x = -4 - 2y

Substitute x = -4 - 2y into the second equation:
4(-4 - 2y) + 8 = -16
-16 - 8y + 8 = -16
-8y = 0
y = 0

Now, substitute y = 0 back into x = -4 - 2y:
x = -4 - 2(0)
x = -4

Therefore, the solution to the system of equations is x = -4 and y = 0.
There is only one solution to this system.
