Answer 1

Answer:-17/6

Step-by-step explanation:

5-t=2........1

5/3-t/2=6.......2

Multiply....2 by 6

10-3t=36.......3

5-t=2...........1

By solving these two equations we get -17/6

Answer 2

Answer:

t = 3

Step-by-step explanation:

Elimination method :

5 - t =2 .......(1)

5/3 -t /2 = 6 .....(2)

(1) × 1/3 » 5/3 -t/3 =2/3

(2)» (-)5/3 (+) t/2 = (-)6

——————————

0 + t/6 = -16/3

t = -16×6 /3

t = -96 / 3

t = -32

Substitution method :

5 - t = 2

- t = -5 + 2

- t = -3

t = 3

sub t=3in (1)

5 - (3) = 2

2 =2
