Answer:

y=8

RS=77, ST=31

Step-by-step explanation:

Note that the entire segment RT is the combined lengths of RS and ST. So:

RT=RS+ST

We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:

108=(9y+5)+(3y+7)

On the right, combine like terms:

108=(9y+3y)+(5+7)

Add:

108=12y+12

Subtract 12 from both sides. The right cancels:

96=12y

Divide both sides by 12:

y=8

So, the value of y is 8.

To find RS and ST, substitute 8 for y. So:

RS=9y+5

Substitute 8 for y:

RS=9(8)+5

Multiply:

RS=72+5

Add:

RS=77

Do the same for ST:

ST=3y+7

Substitute 8 for y:

ST=3(8)+7

Multiply:

ST=24+7

Add:

ST=31
