Question

sovle the pair of linear equation by substitution method:s-t=3:s\3:+t\2=6​

Answer 1

Answer:

s – t = 3 ... (i)

s/3 + t/2 = 6 ... (ii)

From equation (i), we gets = t + 3

Putting this value in equation (ii), we get

t+3/3 + t/2 = 6

2t + 6 + 3t = 36

5t = 30

t = 30/5 ... (iv)

Putting in equation (iii), we obtain

s = 9

∴ s = 9, t = 6
