Question

A system of linear equations is shown below

5x = 3y - 2
y= x + 4
What is the x-coordinate of the solution?

A. 2
B. 4
C. 5
D. 1

Answer 1

If you would like to find the x-coordinate of the solution, you can calculate this using the following steps:

5x = 3y - 2
y = x + 4
_________
5x = 3 * (x + 4) - 2
5x = 3x + 12 - 2
2x = 10
x = 5

The correct result would be C. 5.
