QuestionEvaluate $4a - y$ for $a = 3$ and $y = -4$ .

Studdy Solution

STEP 1

Assumptions1. The value of $a$ is3. The value of $y$ is -4

STEP 2

We are asked to evaluate the expression $4a - y$ . Let's substitute the given values of $a$ and $y$ into the expression.
$4a - y =4() - (-4)$

STEP 3

Now, we simplify the expression by performing the multiplication and subtraction operations.
$a - y =12 - (-)$

STEP 4

Subtracting a negative number is the same as adding its absolute value. So, $12 - (-4)$ becomes $12 +4$ .
$4a - y =12 +4$

STEP 5

Finally, we add the numbers to get the result.
$4a - y =12 +4 =16$ So, when $a=3$ and $y=-4$ , the expression $4a - y$ evaluates to16.

Studdy Solution

STEP 1

Assumptions1. The value of aaa is3. The value of yyy is -4

STEP 2

We are asked to evaluate the expression 4a−y4a - y4a−y. Let's substitute the given values of aaa and yyy into the expression.4a−y=4()−(−4)4a - y =4() - (-4)4a−y=4()−(−4)

STEP 3

Now, we simplify the expression by performing the multiplication and subtraction operations.a−y=12−(−)a - y =12 - (-)a−y=12−(−)

STEP 4

Subtracting a negative number is the same as adding its absolute value. So, 12−(−4)12 - (-4)12−(−4) becomes 12+412 +412+4.4a−y=12+44a - y =12 +44a−y=12+4

STEP 5

Finally, we add the numbers to get the result.4a−y=12+4=164a - y =12 +4 =164a−y=12+4=16So, when a=3a=3a=3 and y=−4y=-4y=−4, the expression 4a−y4a - y4a−y evaluates to16.
