Question

"How do you rearrange a formula?
E.g. Rearrange y = mx + c to make x the subject."

Answer 1

Step-by-step explanation

We're asked to make x the subject (in other words, solve for x) in the equation
`\sf{y=mx+c}`.

So first, subtract c from both sides:

`\sf{y-c=mx}`

Divide each side by m

`\sf{\cfrac{y-c}{m}=x}`

Therefore ,the formula has been rearranged for x.

Answer 2

x =
`(y-c)/(m)`

Explanation:

y = mx + c ( subtract c from both sides )

y - c = mx ( isolate x by dividing both sides by m )

`(y-c)/(m)` = x
