Question

3/4x - 2/3y = 1
3/8x - 1/6y = 4​

Answer 1

Answer:

x=20

y=21

Step-by-step explanation:

3/4x-2/3y=1 (multiply *1/2) elimination method (1)

3/8x-1/6y=4 (2)

adding (1)&(2)

3/8x-2/6y=1/2

3/8x-1/6y=4

by adding we get

1/6y-2/6y=1/2-4

y-2y/6=1-8/2

-y/6=-7/2

-y= -7*6/2

-y= -21

therefore y=21

then write 21 in place of y in any of the equations and you'll get x=20

Hope it helps
