Do not solve the system below. Its solution is (x, y) = (1, 1). Instead, answer the questions. 3x + 4y = 7
5x + 10y = 15

If you were going to solve the system above, what would be the best first step according to the strategy you just learned?

Solve for x in the first equation.

Solve for y in the first equation.
Solve for x in the second equation.
Solve for y in the second equation.
Explain your reasoning.

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
