This is what you have to do:
First what you do is Simplify the equation: 3a + 4b + -5a + 6b = 0
Then just follow the steps below:
Reorder the terms: 3a + -5a + 4b + 6b = 0
Combine like terms: 3a + -5a = -2a -2a + 4b + 6b = 0
Combine like terms: 4b + 6b = 10b -2a + 10b = 0
Solving -2a + 10b = 0
Solving for variable 'a':
Move all terms containing a to the left, all other terms to the right.
Add '-10b' to each side of the equation. -2a + 10b + -10b = 0 + -10b
Combine like terms: 10b + -10b = 0 -2a + 0 = 0 + -10b -2a = 0 + -10b
Remove the zero: -2a = -10b
Divide each side by '-2'. a = 5b
Simplifying a = 5b
