Answer:
We use the basic Arithmetic Properties and the Properties of Equality to rearrange equations:
w = 3(2a + b) - 4
w = 3(2a) + 3(b) - 4 Distributive Property of Multiplication over Division
w = 6a +3b - 4
w - 3b + 4 = 6a Subtraction Property of Equality
6a = w - 3b + 4 Symmetric Property of Equality
a = (w - 3b + 4)/6 Division Property of Equality
