Question

Sue’s couch is 200 centimeters long. It is 16 centimeters less than 3 times the length of the matching chair. How long is the matching chair.

Answer 1

Answer:

The length of the matching chair is $72\ cm$

Step-by-step explanation:

Let

x -----> the length of the matching chair

we know that

The linear equation that represent this situation is

$200=3x-16$

solve for x

Adds 16 both sides

$200+16=3x-16+16$

$216=3x$

Divide by 3 both sides

$216/3=x$

Rewrite

$x=72\ cm$
