a(x-3)+c(x+k)=0

Solution for a(x-3)+c(x+k)=0 equation:

Simplifying
a(x + -3) + c(x + k) = 0

Reorder the terms:
a(-3 + x) + c(x + k) = 0
(-3 * a + x * a) + c(x + k) = 0
(-3a + ax) + c(x + k) = 0

Reorder the terms:
-3a + ax + c(k + x) = 0
-3a + ax + (k * c + x * c) = 0
-3a + ax + (ck + cx) = 0

Solving
-3a + ax + ck + cx = 0

Solving for variable 'a'.

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

Add '-1ck' to each side of the equation.
-3a + ax + ck + -1ck + cx = 0 + -1ck

Combine like terms: ck + -1ck = 0
-3a + ax + 0 + cx = 0 + -1ck
-3a + ax + cx = 0 + -1ck
Remove the zero:
-3a + ax + cx = -1ck

Add '-1cx' to each side of the equation.
-3a + ax + cx + -1cx = -1ck + -1cx

Combine like terms: cx + -1cx = 0
-3a + ax + 0 = -1ck + -1cx
-3a + ax = -1ck + -1cx

Reorder the terms:
-3a + ax + ck + cx = -1ck + ck + -1cx + cx

Combine like terms: -1ck + ck = 0
-3a + ax + ck + cx = 0 + -1cx + cx
-3a + ax + ck + cx = -1cx + cx

Combine like terms: -1cx + cx = 0
-3a + ax + ck + cx = 0
