(z-9)(x+8)=0

Solution for (z-9)(x+8)=0 equation:

Simplifying
(z + -9)(x + 8) = 0

Reorder the terms:
(-9 + z)(x + 8) = 0

Reorder the terms:
(-9 + z)(8 + x) = 0

Multiply (-9 + z) * (8 + x)
(-9(8 + x) + z(8 + x)) = 0
((8 * -9 + x * -9) + z(8 + x)) = 0
((-72 + -9x) + z(8 + x)) = 0
(-72 + -9x + (8 * z + x * z)) = 0

Reorder the terms:
(-72 + -9x + (xz + 8z)) = 0
(-72 + -9x + (xz + 8z)) = 0
(-72 + -9x + xz + 8z) = 0

Solving
-72 + -9x + xz + 8z = 0

Solving for variable 'x'.

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

Add '72' to each side of the equation.
-72 + -9x + xz + 72 + 8z = 0 + 72

Reorder the terms:
-72 + 72 + -9x + xz + 8z = 0 + 72

Combine like terms: -72 + 72 = 0
0 + -9x + xz + 8z = 0 + 72
-9x + xz + 8z = 0 + 72

Combine like terms: 0 + 72 = 72
-9x + xz + 8z = 72

Add '-8z' to each side of the equation.
-9x + xz + 8z + -8z = 72 + -8z

Combine like terms: 8z + -8z = 0
-9x + xz + 0 = 72 + -8z
-9x + xz = 72 + -8z

Reorder the terms:
-72 + -9x + xz + 8z = 72 + -8z + -72 + 8z

Reorder the terms:
-72 + -9x + xz + 8z = 72 + -72 + -8z + 8z

Combine like terms: 72 + -72 = 0
-72 + -9x + xz + 8z = 0 + -8z + 8z
-72 + -9x + xz + 8z = -8z + 8z

Combine like terms: -8z + 8z = 0
-72 + -9x + xz + 8z = 0
