t=14

Cross multiply man, then divide my -1 to get the possitive t your looking for

OpenStudy (anonymous):

can you show how you got there???

OpenStudy (anonymous):

Normal way, you would cross multiply. -t*8 and -7*16. You get -8t = -112. divide by -8: t= -14

OpenStudy (anonymous):

Fast way: multiply (-7/8) by (2/2) because that gives a come denominator and you can cancel it out, your, left with -t = -14, divide by -1 and your answer is t= 14.
