In the context of mathematics, when you add two variables together, such as s + s, you are essentially combining the values of those variables. So, s + s equals 2s, which means you are adding the value of s to itself. Therefore, if we are looking at s + s = t, the expression simplifies to 2s = t.

s is directly proportional to t

2t
S = 3 st + 3t = 6 st = 6 - 3t s = (6 - 3t)/t = 6/t - 3

wth??
s = 7, t = -3
s is directly proportional to t

If you simplify the equation (s+t+s) the answer is 2s+t
T-ty E .
2t
S = 3 st + 3t = 6 st = 6 - 3t s = (6 - 3t)/t = 6/t - 3
Solving for two unknown variables (s and t) requires two independent equations. You have only one.
