Here we go again... can someone explain how these problems work?

Effectus [21]

Answer:

x = 5 only

≡ On a graph, the point touches (5, 0), making <em>x</em> equal to 0.

≡ In other words, you must replace <em>y</em> with <em>0</em> to solve for <em>x. </em>There is no <em>y</em> term in this problem, so you must determine <em>y</em> by separating the coefficients into groups and determining each part.
