Answer:C
In the system of equations above, what is the value of t in terms of s ?
A. B. C. D.
Explanation: C There are a variety of ways to approach this question. You could solve one equation for s or t and substitute it into the other equation, but look to see if you can do it more simply by stacking and adding (or subtracting) the equations. If you double the first equation to get 34s + 40t = 118, you can then stack and subtract the equations to eliminate t and solve for s, as follows:
