Can you solve r=4+7x-sx for x

R = 4 + 7x - sx

7x - sx = r - 4

x (7 - s) = r - 4

x = r - 4 / 7 - s

if we know the value of s and r, we can find the value of x.

there is another way to solve this equation:

r = 4 + 7x - sx

7x - sx = r - 4

7x - sx - (r - 4) = 0

if we put 7x - sx in plce of r - 4, we get

7x - sx - (7x - sx) = 0

7x - sx - 7x + sx = 0

Now 7x - 7x = 0 and sx - sx = 0

So all the terms gives the answer 0

the solution o this equation could not be determined.
