Write in standard form.
3 x + y = 23

Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.
now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,

The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7
2/3x + y = 7
(2/3x + y = 7)3
2x + 3y = 21
The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7 2/3x + y = 7(2/3x + y = 7)32x + 3y = 21
Y= -2/3*x+7 | *3
3y= - 2x+21 | +2x
3y+2x=21 this is the correct answer
You multiply everything by 3 which equals 3y=2x+21 then you switch 21 and 3y which equals -21=2x-3y. Hope this helps
1 Answer. The equation in standard form is 23x−y=7 .
Explanation:
answered: Guest
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.
\frac{2}{5}=\frac{x-18}{x}
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30
so:
