Question

How do you make x the subject of the formula? I need help on this one y= 7x-1​

Answer 1

Answer:

x = 1/7(y+1)

or

x = 1/7 y + 1/7

Step-by-step explanation:

y= 7x-1​

Solve for x

Add 1 to each side

y+1 = 7x-1+1

y+1 = 7x

Divide each side by 7

1/7(y+1) = 7x/7

1/7y + 1/7 =x

Answer 2

Answer:

x=$\frac{y+1}{7}$

Step-by-step explanation:

Hi there!

We want to make x the subject of the formula, which means to solve the formula for x

Here is the given formula:

y=7x-1

Our ultimate goal is to isolate x onto one side

Start by subtracting 7x from both sides

y-7x=-1

Subtract y from both sides to remove it from the left side

-7x=-y-1

Divide both sides by 7

x=$\frac{-y-1}{-7}$

Simplify (factor -1 out of the numerator and denominator, then cancel it out)

x=$\frac{-1(y+1)}{(-1)(7)}$

x=$\frac{y+1}{7}$

Hope this helps!
