Answer:
15
Explanation:
substitute x = 2 and y = 3 into the expression
12x - 3y
= 12(2) - 3(3)
= 24 - 9
= 15
Expression: 2a - b + c
a = 3, b = 4, c = 10
To evaluate such expression, all we have to do is substitute these values to the expression like this:
Therefore 2a + b - c = 12 if a = 3, b = 4, and c = 10.
