The value of x is 4.
Step-by-step explanation:
Consider a Rectangle ABCD
AB as Top
CD as Bottom
AB = -1 + 4x
CD = 3x + 3
To Find:
x = ?
Solution:
In a Rectangle ABCD
Opposite sides of rectangle congruent,
AB = CD
Top = Bottom
on substituting we get
[tex]-1+4x=3x+3\\\\4x-3x=3+1\\\\x=4\\\therefore x =4[/tex]
The value of x is 4.
