Solution for 3A-4B+5A= equation:

Simplifying
3A + -4B + 5A = 0

Reorder the terms:

Combine like terms: 3A + 5A = 8A
8A + -4B = 0

Solving
8A + -4B = 0

Solving for variable 'A'.

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

Add '4B' to each side of the equation.
8A + -4B + 4B = 0 + 4B

Combine like terms: -4B + 4B = 0
8A + 0 = 0 + 4B
8A = 0 + 4B
Remove the zero:
8A = 4B

Divide each side by '8'.
A = 0.5B

Simplifying
A = 0.5B
