Question

Solve the pair of linear equation by substitution method s-t=3 and s/3 +t/2 =6

Answer 1

Answer:

s-t=3

s=3+t......(i)

$\frac{s}{t} + \frac{t}{2} = 6$

put the value of s in the equation

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

$\frac{2(3 + t) + 3t}{6} = 6$

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

5t+6=36

5t=30

t=6

now put the value of 't' in equation (i)

s=3+t

s=9

therefore,t=6,s=9
