I have to find rs and rt

RS= 20

ST= 40

RT=60

Step-by-step explanation:

If you notice, RS and ST make up RT. Therefore, we add RS and ST, and set that equal to RT.

3x-16+4x-8=60               [combine like terms]

7x-24=60                        [add both sides by 24]

7x=84                              [divide both sides by 7]

x=12

Now that we know x, we can plug them into RS.

3(12)-16                          [multiply]

36-16                              [subtract]

20

We can also find ST.

4(12)-8                            [multiply]

48-8                                [subtract

40

true
