Answer:
5x = 20
Step-by-step explanation:
3x - 2y = 8
x + y = 6
To eliminate the y, multiply the second equation by 2:
2x + 2y = 12,
the add that to the first equation:
3x - 2y = 8
2x + 2y = 12
5x + 0 = 20 [or 5x=20, which is the answer desired]
====
The actual value of x is 4: [20/5]. We can do a similar elimination of the x to find that y = 2. This solution, (4,2), is the point at which the two lines, formed by these two equations, meet. See attachment.
x = 4
