S is the midpoint of stack R T with bar on top. If RS = 7x - 3 and ST = 3x + 1, then what is the value of x?

The value of x is 1.

Step-by-step explanation:

Given that S is the midpoint of RT so we can assume that RS is equal to ST. Next, we have to compare it :

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
