2x-4y=8
Y=3/2x
solution

(- 2, - 3 )

Step-by-step explanation:

Given the 2 equations

2x - 4y = 8 → (1)

y = x → (2)

Substitute y = x into (1)

2x - 4( x ) = 8

2x - 6x = 8

- 4x = 8 ( divide both sides by - 4 )

x = - 2

Substitute x = - 2 into (2) for corresponding value of y

y = × - 2 = - 3

Solution is (- 2, - 3 )

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
