Equation.
1/2 m - 3/4 n = 16
n = 18
Substitution.
1/2 m - 3/4(18) = 16
1/2 m - 13.5 = 16
1/2 m =16 +13.5
1/2 m = 29.5
m = 29.5 × 2
m = 59
Hi!
I would approach this question by first looking at where the parallelogram is located, by graphing the image. I did so and drew a rough image on Paint (See attached image)
To get the part where the diagonals intersect, I would find the midpoint of the line between points (1, 3) and (5,-9) (or the other pair). The reason is a parallelogram's diagonals always bisect each other, meaning the point they intersect is always the middle of the two diagonals.
Therefore, you can find the midpoint of a diagonal, between (1, 3) and (5, -9). The midpoint theorem is (
.
Take the points (1, 3) and (5, -9), and fill them in.

Then solve.

(3, -3)
If you'd like to check the other midpoint:
Take the points, (8, 3) and (-2, -9)

Then solve.

(3, -3)
They're the same, so that answer is correct.
Hope this helps!
