To determine the value of a, we substitute the corresponding y-value of the point to the equation of the graph and solve for x. The given equation is a linear equation so its graph should be a line. We calculate "a" as follows:
5x + y = 8
5a + 3 = 8
5a = 8 - 3 = 5
a = 1
51 = 3 * 17, sum of 20, no good.
<span>52 = 2 * 2 * 13, sum of 17, no good. </span>
<span>54 = 2 * 3 * 3 *3, sum of 11. </span>
<span>The answer is 54. If you need more help, let me know.</span>
