Make t the subject of the formula: S = at + bt

Answers

Answer 1

Answer: To make t the subject is basically isolating t

S = at + bt
We see on the right side that t is common, so we factor it out.

S = t(a + b)
Divide by (a+b) to isolate t

$(S)/(a + b) = (t(a+b))/((a+b))$
a + b and a + b cancels out
We are left with the answer:
t = $(S)/(a+b)$

Answer 2

Answer: $S = at + bt \n t(a+b)=S\n t=(S)/(a+b)$
