There is a special kind of substitution which some books call it by comparison.
When the two equations are both
y=some function of x
y=some other function of x, then
we can substitute the second equation into the first giving
some function of x = some other function of x and start solving.
For example,
<span>y = –2x + 8
y = x – 1
substitute second into first
x-1=-2x+8
isolate x on left,
3x=9
x=3
second step is to substitute x=3 into second equation to get
y=x-1=3-1=2
Therefore the solution is (3,2)</span>

Hello!
The midpoint formula is basically an average of x and y.
It is also written as: 
.
With the formula above, we can substitute the given points into the equation, and simplify.
Therefore, the midpoint between points H and J is choice D, (6, 3.5).
