x(-10(10 + a) + a(10 + a)) = 200
x((10 * -10 + a * -10) + a(10 + a)) = 200
x((-100 + -10a) + a(10 + a)) = 200
x(-100 + -10a + (10 * a + a * a)) = 200
x(-100 + -10a + (10a + a2)) = 200

Combine like terms: -10a + 10a = 0
x(-100 + 0 + a2) = 200
x(-100 + a2) = 200
(-100 * x + a2 * x) = 200

Reorder the terms:
(a2x + -100x) = 200
(a2x + -100x) = 200

Solving
a2x + -100x = 200

Solving for variable 'a'.

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

Add '100x' to each side of the equation.
a2x + -100x + 100x = 200 + 100x

Combine like terms: -100x + 100x = 0
a2x + 0 = 200 + 100x
a2x = 200 + 100x

Divide each side by 'x'.
a2 = 200x-1 + 100

Simplifying
a2 = 200x-1 + 100

Reorder the terms:
a2 = 100 + 200x-1

-100 + a2 + -200x-1 = 100 + -100 + 200x-1 + -200x-1

Combine like terms: 100 + -100 = 0
-100 + a2 + -200x-1 = 0 + 200x-1 + -200x-1
-100 + a2 + -200x-1 = 200x-1 + -200x-1

Combine like terms: 200x-1 + -200x-1 = 0
-100 + a2 + -200x-1 = 0
