Dividing fractions is the same as multiplying by its reciprocal so you can change the equation to this
And you can simplify by eliminating the fours and multiplying straight across
You can pull out - 7 from the top and 2 from the bottom so you have this
And then you can cancel out to (2-x) to get an answer of

Answer:
4
Step-by-step explanation:
So we know that RT is 36.
Note that RT is the combined length of RS and ST. Therefore:
Substitute. RT is 36, RS is 6x+1 and ST is x+7:
Combine like terms and add:
Subtract 8 from both sides:
Divide by 7:
So, our answer is 4 :)
