Let

x-------> the length of the rectangle

y------> the width of the rectangle

we know that

the perimeter of the rectangle is equal to

[tex]P=2x+2y[/tex]

[tex]P=190\ in[/tex]

so

[tex]2x+2y=190[/tex]------> equation A

[tex]y=4\ in[/tex] ------> equation B

substitute equation B in equation A

[tex]2x+2*4=190[/tex]

[tex]2x+8=190[/tex]

therefore

the answer is

[tex]2x+8=190[/tex]
