Question

solv the equation and check your answer 4 (2y-3)+5 (3y-4)=14

Answer 1

8y-12+15y-20=14

23y-32=14

23y=46

y=2

Answer 2

4 ( 2y - 3 ) + 5 ( 3y - 4 ) = 14

8y - 12 + 15y - 20 = 14

8y + 15y - 12 - 20 = 14

23 y - 32 = 14

23y = 14 + 32

23y = 46

y = 46 / 23

y = 2




for clarification :

put Y = 2 in equation :

L.H.S :

4 ( 2y - 3 ) + 5 ( 3y - 4 )

4 ( 2*2 - 3 ) + 5 ( 3*2 - 4 )

4 ( 4 - 3 ) + 5 ( 6 - 4 )

4 * 1 + 5 * 2

4 + 10

14



L.H.S = R.H.S
