I can't see the options, but you would need to multiply (4x - 2y = 7) by 3, and (3x - 3y = 15) by 4 so that you get 12x in both equations. Then when you subtract, you eliminate 12x. I hope this helps!

Find the midpoint of X (26,56) and Y (26,1)

Svetradugi [14.3K]

Answer:

(26, $\frac{57}{2}$ )

Step-by-step explanation:

Hi there!

We are given the coordinates (26, 56) and (26, 1)

We want to find the midpoint of these two points

The midpoint can be found using the formula $(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2})$ , where $(x_1, y_1)$ & $(x_2, y_2)$ are points

We have 2 points, which is what we need to find the midpoint, but let's label the values of the points to avoid confusion and mistakes when actually calculating

$x_1=26\\y_1=56\\x_2=26\\y_2=1$
