Check the picture below.

the quadrilateral is a parallelogram, thus the diagonals bisect each other, so, we could have used either diagonal, and get the same midpoint.

Solve for x: 20 = 3x -1
Feliz [49]

20=3x-1

move -1 to the other side

sign changes from -1 to +1

20+1=3x-1+1

20+1=3x

21=3x

divide both sides by 3 to get x by itself

21/3=3/3x

Cross out 3 and 3, divide by 3 and then becomes 1*1*x=x

21/3=x

Answer:

x=7
