Question

Please help I’m on the middle of an exam Use the diagram of ABCD to find x.

Answer 1

This is like property of a parallelogram you have to do is basically follow its properties which is opposite sides are congruent

so we solve like this

$x+3=2x-5$

subtract -3 on each side one is canceled since its equal to zero

and other is -3-5= -8

$x=3x-8$

now subtract -3 on each side

-3x-x is -4 so,

-4x=8

divide its equal to 2

X=2

Hope it helps! have an awesome day you should probably study the properties of parallelogram
