Final answer:
To evaluate the expression 6a + 4b - 6 when a = 1 and b = 3, substitute the values into the expression and simplify.
Step-by-step explanation:
To evaluate the expression 6a + 4b - 6 when a = 1 and b = 3, we substitute the given values into the expression.
Plugging in a = 1 and b = 3, we get:
6(1) + 4(3) - 6 = 6 + 12 - 6 = 12.
