What is the value of x in the following system?

y = 3x - 5

6x + 3y = 15

x = 2

Step-by-step explanation:

I used the process of substitution to do this.

1. put both equations into slope-intercept form:

y = 3x - 5

y = - 2x + 5

2. since they both equal y, they must equal each other:

3x - 5 = - 2x + 5

3. simplify:

2 = x
