How would you evaluate the expression 3x 4y equals 9 when x equals 2 and y equals 5?
3x + 4y = 9 is an equation, a statement that states the two expressions 3x + 4y and 9 are equal. We like to know if there are any values of the variables x and y that will make the statement a true one. In our case, we're going to check if x = 2 and y = 5, will satisfy the given equation. In other words, if we substitute the corresponding values of x and y into the equation and the left side will equal to the right side, then (2, 5) is a solution. Otherwise, it's not. Check: 3x + 4y = 9; x = 2 and y = 5 3(2) + 4(5) =? 9 6 + 20 =? 9 26 = 9 False Therefore, (2, 5) is not a solution.

What is two step equation that equals 23?
A two-step equation that equals 23 could be represented as (2x + 5 = 23). To solve for (x), first subtract 5 from both sides to get (2x = 18), and then divide by 2, resulting in (x = 9).
How do you do a 2 step equation?
When you are solving a 2-step equation, you do the opposite of a 1-step equation. You do addition and subtraction first, then the multiplication second. Example: 2x + 9=16 -9 -9 2x=7 Now it's a 1-step equation 2x=7 /2 /2 Your answer would be 3.5 To check all you do is replace the variable with your answer. 2x + 9=16 2(3.5) + 9=16
