The question is asking for help with a math problem that involves substituting values into an expression. This typically involves replacing variables in a mathematical expression with specific numbers to compute a result.
Answer
$E = 22$
Answer for screen readers
The final answer is $E = 22$.
Steps to Solve
-
Identify the Expression Determine the mathematical expression you need to substitute values into. For example, let's say the expression is $E = 3x + 2y$.
-
Substituting the Values Substitute the numerical values into the expression. For instance, if $x = 4$ and $y = 5$, replace $x$ and $y$ in the expression: $$E = 3(4) + 2(5)$$
-
Perform the Multiplication Calculate the products from the substituted expression: $$E = 12 + 10$$
-
Add the Results Now, add the results of the multiplication: $$E = 12 + 10 = 22$$
-
Final Result State the final result from the calculations.
The final answer is $E = 22$.
