A. t = $3, s = $4
B. t= $12, s = $8
C. t = $4, s = $1
D. t = $8,5 = $12

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

It means if x is -1 what is y then . check -1 on x axis and then check the value of y when x is -1
