Answer:
Simplifying
2ab + 3bc + -5ab + bc = 0
Reorder the terms:
2ab + -5ab + 3bc + bc = 0
Combine like terms: 2ab + -5ab = -3ab
-3ab + 3bc + bc = 0
Combine like terms: 3bc + bc = 4bc
-3ab + 4bc = 0
Solving
-3ab + 4bc = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4bc' to each side of the equation.
-3ab + 4bc + -4bc = 0 + -4bc
Combine like terms: 4bc + -4bc = 0
-3ab + 0 = 0 + -4bc
-3ab = 0 + -4bc
Remove the zero:
-3ab = -4bc
Divide each side by '-3b'.
a = 1.333333333c
Simplifying
a = 1.333333333c
