Simplifying
1.3b + 7.8 + - 3.2b = 0
Reorder the terms:
7.8 + 1.3b + - 3.2b = 0
Combine like terms: 1.3b + - 3.2b = - 1.9b
7.8 + - 1.9b = 0
Solving
7.8 + - 1.9b = 0
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-7.8' to each side of the equation.
7.8 + - 7.8 + - 1.9b = 0 + - 7.8
Combine like terms: 7.8 + - 7.8 = 0.0
0.0 + - 1.9b = 0 + - 7.8
-1.9b = 0 + - 7.8
Combine like terms: 0 + - 7.8 = - 7.8
-1.9b = - 7.8
Divide each side by '-1.9'.
b = 4.105263158
Simplifying
b = 4.105263158
