Answer:

3

Step-by-step explanation:

We want to cancel out the 3y.  The second equation has a -y so if we multiply that by 3 we'll get -3y and when we add the ys go away.

Answer:

Step-by-step explanation:

Answer:

Multiply the 2nd row by 3.

Step-by-step explanation:

Multiply the second row by 3.  Then we have:

2x + 3y = 18

21x - 3y  = 30

Now, if we combine these two equations, y will disappear and we'll have:

23x = 48, so that

x = 48/23.

If the equal is 55x + 35y = 200

x: time-driven at 55 miles/hour

y: time-driven at 35 miles/hour

If the car spends 2.5 hours at 35 miles per hour, then it drove:

 55x + 35(2.5) = 200

    55x =35

       y = 112.5

There the drive spent about 2.5-hour driving at 55 mph.

Hope it helps!
