If 3x + 5y = 6 and 2x + y = 4, what is x?

answer:

these teacher are mean

x=2

y=0

lets make it easier

step-by-step explanation:

if 3x + 5y = 6 and 2x + y = 4, what is x?

3x + 5y = 6

2x + y = 4, (easier is better i complicated it

2(2)+0=4

3(2)+5(0)

6+0=6

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
