Question

Evaluate the expression when a = 1/4 and b = 6 12a + (b - a - 4)

Answer 1

1

Explanation:

Substitute a and b .

12 * 1/4 + ( 6 - 4 - 4)

Calculate the difference

12 * 1/4 + ( -2 )

Cancel out the greatest common factor of 4

3 + ( -2 )

When there is a + in front of an expression in the parentheses, the expression remains the same

3 - 2

Subtract the numbers

1

So the solution is, 1
