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:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.
