Question

3(x+2y) =10y+5
2(x+2y) =3x+2

Answer 1

Answer:

y = 11/8 , x = 7/2

Step-by-step explanation:

3(x+2y) =10y+5. ------------- ( 1 )

2(x+2y) =3x+2. ------------ ( 2 )

( 1 )-------- 3x - 5 = 4y

( 2 )-------- x = 4y - 2

from ( 1 ) & ( 2 ) we get,

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

12y - 6 - 5 = 4y

12y - 4y - 11 = 0

8y = 11

y = 11/8

in eq. ( 2 )

x = 4 ( 11/8 ) - 2

= (11 - 4) ÷ 2

x = 7/2
