Answer:
x=2
Step-by-step explanation:
Answer: x = 3. the length of side ST is 14.
Step-by-step explanation:
Since both sides are equal, we can use the equation 3x + 5 = 5x - 1.
To start the problem, we subtract 3x from each side which makes our equation 5 = 2x - 1.
The next step would be to simplify the equation by adding 1 to each side which makes our equation 6 = 2x.
We then need to simplify the equation to x = 3.
This means the answer to 9 is x = 3.
For the next problem, since we already know the value of x, we substitute its value which in this case would be 3. This leaves us with an equation of 9 + 5, which equals 14.
This means the length of side ST is 14.

-3/4 + 2/5 x = 7/20 x - 1/2
2/5 x = 7/20 x - 2/4 + 3/4
2/5 x = 7/20 x + 1/4 (first option - Yes)
second option - No
-3/4 + 2/5 x = 7/20 x - 1/2
-3/4 = 7/20 x - 8/20 x - 1/2
-3/4 = -1/20 x - 1/2 (third option - Yes)
-3/4 + 1/20 x = -1/2 (fifth option - Yes)
fourth option - NO
Answer:
2/5 x = 7/20 x + 1/4 (first option)
-3/4 = -1/20 x - 1/2 (third option)
-3/4 + 1/20 x = -1/2 (fifth option)
