Question

What is the general solutions of ½ + 4y = 10.

Answer 1

Explanation:

Method 1:

1/2 + 4y = 10

=> 4y = 10 - 1/2

= (20 - 1)/ 2

= 19 / 2

=> y = 19/ 2x4

= 19 / 8

= 2 3/4

Therefore y = 2 3/4. ------ (Answer)

Method 2:

1/2 + 4y = 10

=> Multiplying the whole equation by 2.

=> 2 x (1/2 + 4y = 10)

=> 1 + 8y = 20

=> 8y = 20 - 1

= 19

=> y = 19/8

= 2 3/4

Therefore y = 2 3/4 --------- (Answer)
