Do not solve the system below. Its solution is (x, y) = (1, 1). Instead, answer the questions.3x + 4y = 75x + 10y = 15If you were going to solve the system above, what would be the best first step according to the strategy you just learned?

The second equation, 5x + 10y = 15, can be simplified by dividing every term by 5 to get x + 2y = 3. Then x has a coefficient of 1, so it is straightforward to isolate x: x = 3 − 2y. Thus, the best first step is to solve for x in the second equation.
