First, get in standard form.
3X - Y = 21
-Y = -3X + 21
Y = 3X - 21
now set both variables equal to 0 to find intercepts/values
3X - 21 = 0
3X = 21
X = 7
----------
Y = 3(0) - 21
Y = - 21
no
x = ab x = 21*37 x = 777
x/5 = 8/21 x = 8/21 * 5 x = 1.904761905
3xy
29
The answer is that the value of x is -21
no
(x + 6y)(x - 3y)
-3xy is a monomial where x and y are variables and -3 is the coefficient of the monomial.If we know the value of y, we have to substitute it for y, and we say that -3(y-value) is the coefficient of x.
The value of x is -21.
The value of x is 29
2(2)2 + 3(2)(- 4) - 4(- 4)2 8 - 24 - 64 = - 80 ======
14
It is an equation and the value of x is 7
If x/3 = 7 then the value of x is 21

They are: (3, 1) and (-11/5, -8/5)
