Question

Someone please help explain how to find x

Answer 1

Step-by-step explanation:

In parallelogram , opposite sides are equal to one another.

Therefore,3x+7=5x-17

=> -2x= -24

=>x= 12

Answer 2

Answer:

x=12

Step-by-step explanation:

In a parallelogram opposite sides are equal

Therefore:

$3x + 7 = 5x - 17$

and

$5y - 20 = 2y + 25$

To find x move all the terms from the right side to the left side or vice versa. I'll use the left this time (Remember that when you transfer, the positive number becomes the negative and the negative number becomes positive)

$5x - 3x - 17 - 7 = 0$

$2x - 24 = 0$

Transfer 24 to the other side

$2x = 24$

Divide both by 24

$\frac{2x = 24}{2}$

$x = 12$
