What is the solution to y=x+16 and y=-x+4??

BaLLatris [955]

<span>y=x+16
y=-x+4

All you have to do is substitute.
Put the second equation into the first equation.

-x + 4 = x + 16
4 = 2x + 16
-12 = 2x
-6 = x

Now substitute the x into one of the equations to get y.

y = (-6) + 16
y = 10

The solution to these equations is (-6, 10).</span>

o-na [289]

We can compare by converting Johnny's reading time into the same unit of Jacky's, hours.

There are 60 minutes in an hour, so use this:

$\frac{1}{3} * \frac{60}{1} = 20$

15 < 20, so Johnny read faster. This is 5 pages faster per hour than Jacky.
