Question

6u +3s = 6 , 2u + 4s = 5 by cross multiplication method​

Answer 1

Answer:

The values of u and s are;-

u=1/2

s=1

Answer 2

Answer:

6u+3s=6 ....×1

2u+4s=5...×3

6u+3s=6

6u+12s=15

( - ) (-). (-)

0. -9s= -9

s= -9 ÷ -9

s=1

therefore, putting the value of s in equation 1

so,

6u+3×1=6

6u+3=6

6u=6-3

6u=3

u=3÷6

u=1\2

Hence s=1

u=1\2...Ans
