Question

What is the solution to the system of equations below?

x + 8
y = 3 - 12

A) 0
B) 21.2
C) 21.10
D) -21.16

Answer 1

The solution to the system of equations given can be found to be x = 10 and y = 18.

How to find the solution?

You can solve this system of equations by setting the two equations equal to each other since they both equal y:

y = x + 8

y = 3x - 12

Set them equal to each other:

x + 8 = 3x - 12

Isolate the variable x. First, subtract x from both sides:

8 = 2x - 12

20 = 2x

x = 20 / 2

x = 10

Use the first equation:

y = x + 8

y = 10 + 8

y = 18

So, the solution to the system of equations is x = 10 and y = 18.
