Write y =1/3 x + 7 in standard form using integers. -x + 3y = 21 -x - 3y = 21 -x + 3y = 7 3x - y = 21

-x+3y=21

Step-by-step explanation:

times 3

3y=x+21

-x+3y=21

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
