Reorder the terms:
-4qrst + 9qrstx = qrst(-20 + 7x)
-4qrst + 9qrstx = (-20 * qrst + 7x * qrst)
-4qrst + 9qrstx = (-20qrst + 7qrstx)

Solving
-4qrst + 9qrstx = -20qrst + 7qrstx

Solving for variable 'q'.

Move all terms containing q to the left, all other terms to the right.

Add '20qrst' to each side of the equation.
-4qrst + 20qrst + 9qrstx = -20qrst + 20qrst + 7qrstx

Combine like terms: -4qrst + 20qrst = 16qrst
16qrst + 9qrstx = -20qrst + 20qrst + 7qrstx

Combine like terms: -20qrst + 20qrst = 0
16qrst + 9qrstx = 0 + 7qrstx
16qrst + 9qrstx = 7qrstx

Add '-7qrstx' to each side of the equation.
16qrst + 9qrstx + -7qrstx = 7qrstx + -7qrstx

Combine like terms: 9qrstx + -7qrstx = 2qrstx
16qrst + 2qrstx = 7qrstx + -7qrstx

Combine like terms: 7qrstx + -7qrstx = 0
16qrst + 2qrstx = 0
