Question

Help me pls im confused
Using the following image, solve for SR.

Answer 1

2x+23+x+21=14

3x+44=14

3x+44-44=14-44

3x=-30

3x÷3=-30÷3

x=-10

SR=2x+23

(2*-10)+23

-20+23

3

SR=3

Explanation:

14 is the length of the line

so we add equation of SR and RQ to get full line equation

search for x

the answer is x=-10

Then, substitute -10 for x in 2x+23 to find out the length for SR

you'll get the answer 3
