<span>4x + 3y = 16
7x + 6y = 31

Note what happens if we mult. the first eqn. by -2:  

-8x - 6y = -32

Combining this with the 2nd equation eliminates the variable y:

</span>-8x - 6y = -32<span>
7x + 6y = 31
--------------------
-x          = -1, or x = 1.  Sub 1 for x in either of the 2 given eqns to find y:

For example:  4(1) + 3y = 16, so 36 = 12, and y = 3.  Sol'n is (1,3).</span>

yaroslaw [1]

Answer:

(-1, 1)

Step-by-step explanation:

Midpoint formula: (x₁ + x₂/2 , y₁ + y₂/2)

Substitute the values into the formula.

(-5 + 3/2 , 3 - 1/2)

(-2/2 , 2/2)

(-1,1)

Therefore, the midpoint is (-1, 1).
