Answer:
<h3>
Evaluating an expression</h3>
Unlike an equation, expression does not have an equal sign.
Example
(x² - 4²) / (x + 2)
So, by evaluating an expression it means to simplify the expression. Let's take a look at the example again
(x² - 4²)
= (x + 2)(x - 2) / (x + 2)
= (x - 2)
<h3>Solving an equation</h3>
Solving an equation involves finding an unknown value given in the equation. It contains an equal to sign (=) so, it result in a solution.
Example
(x² - 4²) / (x + 2) = 0
(x + 2)(x - 2) / (x + 2) = 0
(x - 2) = 0
x = 2
24 is the 8% so let's set up a proportion.
Part/whole = %/100
24/x = 8/100
X = 300
Your answer is wrong, sorry
Answer:
<h2>-46</h2>
Step-by-step explanation:
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
