First you want to distribute
2x + 8 = 24
-8 -8 Subtract 8 from both sides
2x = 16
then divide by 2
x=8

Use the order of math operations:

PEMDAS
(You might remember this as "Please excuse my dear Aunt Sally.")1

1. Parentheses
2. Exponents
3. Multiplication and Division
4. Addition and Subtraction

Always do parentheses first....but since you have a variable you can't add 4 to x, move on......no exponents......so, multiply.....

2x +8=24

Can you do the rest by yourself?

Get the x on the side by itself - subtract 8 from each side, then divide by 2 to see what x equals.

When you get your answer, remember to put that number back in the original equation in place of the x to see if it works.

multiply the number outside the bracket with all the numbers within the bracket.
here we have 2 outside the bracket.
so it becomes 2x + 8 =24
2x = 24-8
2x = 16
x = 8

first step is divide both sides by 2
2(x+4)/2=24/2
x+4=12
x+4-4=12-4
x=8
check
2(8+4)=2*12=24
checks

2(x+4)=24
times x and 4 by 2
2x+8=24
-8 -8
2x=16
divide both sides by 2
x=8

distribute.

(2*x)+(2*4)=24

2x=16
x=8

1st neutralize the multiplier by dividing by itself...(divide both sides by 2). Then deduct four from each side. Email me if you're stuck for the whole answer.
