Question

solve it by substitution method with explanation

Answer 1

Given Equation is s - t = 3.

= > s = 3 + t  ------ (1)

Given Equation is s/3 + t/2 = 6  ------ (2)

Substitute (1) in (2), we get

$= \ \textgreater \ \frac{3 + t}{3} + \frac{t}{2} = 6$

= > 2(3 + t) + 3t = 36

= > 6 + 2t + 3t = 36

= > 6 +5t = 36

= > 5t = 36 - 6

= > 5t = 30

= > t = 30/5

= > t = 6.


Substitute t = 6 in (1), we get

= > s - t = 3

= > s - 6= 3

= > s = 9


Therefore the value of s = 9 and t  = 6.


Hope this helps!

Answer 2

simply try to solve this if u ur self try to solve this u will get some extra knowledge also
nd I think u are a intelligent student to do it
