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 :)
Positive × Positive = Positive
3 × 2 = 6
m × n = mn
Positive × Negative = Negative
8 × -4 = -32
m × -n = -mn
Negative × Negative = Positive
-5 × -4 = 20
-m × -n = mn
(-x) × (-x) = x²
The same rules apply for division as multiplication.
