It's your turn now.
I'll be glad to check your answer.
To evaluate the expression -a + 7y when a = 2 and y = -4, you need to substitute the given values into the expression and perform the arithmetic.
Step 1: Substitute the values for a and y into the expression.
-a + 7y = -(2) + 7(-4)
Step 2: Simplify the expression by performing the arithmetic.
-(2) + 7(-4) = -2 - 28
Step 3: Continue simplifying the expression.
-2 - 28 = -30
Therefore, when a = 2 and y = -4, the expression -a + 7y evaluates to -30.
