Question

Make k the subject of 7k=4k/3t-11t

Answer 1

Multiply 4k to 7k. Then divide 3t-11t by 7x4. Then square root the rest

Answer 2

We are given the equation $7k=\frac{4k}{3t}-11t$

In order to make k the subject, we will have to isolate k and express it in terms of the other variable, t. Let us begin:

Multiply both sides by 3t

$21kt=4k-33t^2$

Let us now subtract 4k from both sides:

$21kt-4k=-33t^2$

Take k out as the common factor on the left hand side of the above equation:

$k(21t-4)=-33t^2$

Divide both sides by 21t-4

$k=\frac{-33t^2}{21t-4}$

If we multiply the numerator and the denominator on the right side by -1 we will get, k to be as:

$k=\frac{33t^2}{4-21t}$

The above the given equation expressed with k as the subject.
