a = 4 + - 1.333333333b
Step-by-step explanation:
Simplifying
3a + 4b = 12
Solving
3a + 4b = 12
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.
3a + 4b + - 4b = 12 + - 4b
Combine like terms: 4b + - 4b = 0
3a + 0 = 12 + - 4b
3a = 12 + - 4b
Divide each side by '3'.
a = 4 + - 1.333333333b
Simplifying
a = 4 + - 1.333333333b
