An equation is given.

y = 3x + c

Create an equivalent equation by solving for x in terms of y and c.

X = (y - c) / 3 OR X = (y/3) - (c/3)

Step-by-step explanation:

If y = 3x + c

And we are made to make "X" the subject of the formula also known ad solving for "X", all we need to do is

Firstly, subtract both sides by c to leave out only x at one side of the equality sign

Y = 3x + c

Subtracting both sides by c, we have

Y - c = 3x + c - c

y - c = 3x.

Secondly, divide both sides by 3 so as not to have any coefficient for x

(Y - c) : 3 = 3x : 3

(y - c) / 3 = x

X = (y - c) / 3 OR X = (y/3) - (c/3)

Answer: x = 1/3y + 1 / 3 c

Step-by-step explanation:

Hi, to answer this question we have to solve for x:

y = 3x + c

3x + c = y

isolating x (the whole term)

3x = y + c

x = (y+c) / 3

Applying distributive property

x = (y: 3) + (c : 3)

x = 1/3y + 1 / 3 c
