At which point will the lines 5x + 2y = 36 and x − y = 3 meet on the graph?

Answer and explanation

Correct answer: (6, 3)

The correct answer is A, (6, 3). The intersection point must satisfy both equations at the same time. Test or solve systematically. From x − y = 3, we get y = x − 3. Substituting in the first equation gives 5x + 2(x − 3) = 36, so 7x − 6 = 36, 7x = 42, and x = 6. Then y = 6 − 3 = 3. Therefore the intersection is (6,3). Option A satisfies both: 5(6)+2(3)=36 and 6−3=3. Option B gives 20+12=32, not 36. Option C gives 15+12=27, not 36. Option D gives 25+8=33, not 36. A graphically obtained intersection should always be checked by substitution in both equations.
