Question

If RT=36, find the value of x

Answer 1

4

Explanation:

So we know that RT is 36.

Note that RT is the combined length of RS and ST. Therefore:

`RT=RS+ST`

Substitute. RT is 36, RS is 6x+1 and ST is x+7:

`36=(6x+1)+(x+7)`

Combine like terms and add:

`36=7x+8`

Subtract 8 from both sides:

`28=7x`

Divide by 7:

`x=4`

So, our answer is 4 :)
