`y = 5`

Explanation:

The graph is in the attached image above

Answer 2

• (2, 5)

=======================

Given equations:

• y - 2x = 1 and
• 2y - x = 8

Solve by graphing, graph each line and find the point the lines intersect, this point is the solution.

See the attached, the solution is (2, 5)
