Question

DEFG is a rumbus. Find the vaule

Answer 1

Explanation:

The sides of a square are equal to each other, it is with the same with rhombus.

With this information, we can Say that
`DE` is equal to line
`GD`, with

`DE =7x-4GD=3x+12`

`7x-4=3x+12\\`
Take
`3x` from both sides.

`4x-4=12`
Add 4 to isolate X

`4x=16`
Divide by 4

`x=4\\`

So we can say that the value of
`x` is 4

Answer 2

Explanation:

in a rhombus (not rumbus !) all sides are equally long.

that means

7x - 4 = 3x + 12

4x = 8

x = 2
