Rewrite the equation 4x – 6y = –30 as a function of x.?

Answer 1

x= (-30+6y)/4

Answer 2

This means solve for x.

When you solve for x, you must get all of the other variables to one side of the equation, and in order to do that you must do the opposite of what has been done thus far.

Step 1 Add 6y to both sides of the eqn
The 6ys on the left will cncel out leaving 0 and the there will be 6ys on the right
This gives you (4y=6y-30)

Step 2 Divide both sides of the eqn by 4 to isolate x
The 4s on the left side will cancel, leaving x and the fours on the right will be divided into the numbers already existing
This gives you x=(3/2)y-(15/2) or in decimals x=1.5y-7.5

Answer 3

All yet between the above solutions are incorrect. A function of x potential that x is the self reliant variable, meaning you're no longer fixing for x yet for y. through fact of this you customarily see y = f(x), meaning that y is a function of x. the different posters sparkling up for x, and are honestly rewriting the equation as a function of y, which isn't what your question is looking. So, y = f(x) = (4x + 30) / 6 = (2/3)x + 5.

Answer 4

4x -6y = -30
4x = 6y -30
x = 6/4 y - 30/4
x = 3/2 x - 15/2 is the final answer

Answer 5

4x - 6y = -30
-6y = -30 - 4x
6y = 30 + 4x
y = 30/6 + 4/6x
y = 5 + 2/3x

Answer 6

4x- 6y= -30
4x-6y+30=0
4x+30 = 6y
(4x + 30) / 6 = y
f(x)= 4x +30 / 6

Answer 7

-30+6y=4x

(1/4)(-30+6y)=x

Answer 8

x=-30/4-6y

Answer 9

*-*Okay you add 6y to both sides{meaning add 6y to 6y and that leaves you with none...then you add 6y to the negative 30 and you get...negative 24...and you divide 4x into the negative 24 which gives you negative 6...*-*Hopefully i helped you*-*

Answer 10

x= -30 + 6y.
