If 2t+(s-r)/3= t what is s in terms of r and t?

Step 1. Let's get rid of denominator by multiplying 3 to both sides of equation:

Step 2. Add -6t+r to both sides of equation to get s.

ANSWER

Step 3. So s=-3t+r

I hope the above steps were helpful.

equation is 2t + (s-r)/3 = t
solve for s.
multiply both sides of the equation by 3 to get:
2*3*t + s - r = 3*t
add r and subtract 2*3*t from both sides of the equation to get:
s = 3*t - 2*3*t + r
this becomes:
s = 3t - 6t + r which becomes:
s = -3t + r
-----
if you let t = 1 and r = 1, you get s = -3 + 1 = -2
-----
if you substitute s = -2 and t = 1 and r = 1 into the original equation you get:
2t + (s-r)/3 = t becoming:
2 + (-2-1)/3 = 1 which becomes:
2 -(3/3) = 1 which becomes:
1 = 1 which is true so the value for s is good.
-----
your answer is:
s = -3t + r
