Question

2t+1=5s+ 4
3t+ 2=2s+1
find out & the value of
'ť& 's',​

Answer 1

Answer:

s = -1 t= -1

Step-by-step explanation:

2t +1 =5s+4

2t - 5s = 4-1

2t - 5s = 3 ----------(1)

3t +2=2s+1

3t - 2s = 1-2

3t-2s=-1 ------------(2)

from (1) and (2)

2t - 5s = 3 × 3

3t - 2s = -1 × 2

6t - 15s = 9

6t - 4s = -2

(-)(+) (+)

________

0 - 11t = 11

t= - 11/11

t= -1 -----------(3)

put (3) in (1)

2(-1) -5s = 3

-2 -5s = 3

-5s = 3+2

-5s =5

s = 5/-5

s = -1
