Question

Two lines, C and D, are represented by the equations given below:

Answer 1

If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:

y = x + 12
y = 3x + 2
______________
y = y
x + 12 = 3x + 2
12 - 2 = 3x - x
2x = 10
x = 5

y = x + 12 = 5 + 12 = 17

The correct result would be (x, y) = (5, 17); because both lines pass through this point.
