PEMDAS

When solving an equation we do them in reverse order

AS adding and subtracting

MD multiplication and division

E exponents

Basically we are trying to get the variable alone.

12=10-3x

subtract 10 from each side

then divide by -3 on each side

3/5 x -12 = 18

first add 12 to each side

then multiply by 5/3 to each side

Answer:

x = 16

Step-by-step explanation:

Let the unknown number be x.

Translating the word problem into an algebraic expression, we have;

4x + 9 = 73

4x = 73 - 9

4x = 64

x = 64/4

x = 16

Therefore, the unknown number is 16.

What is 9+9(2+4)÷3-2 equal

lesantik [10]

First, we must follow PEMDAS. (Parenthesis, exponents, division, multiplication, addition, and subtraction.).

We do what's in the parenthesis first.

9+9(2+4)÷3-2.

2+4=6.

Now our problem looks like this;

9+9(6)÷3-2
OR
9+9×6÷3-2.

Anything in a parenthesis with no sign next to it, like this; 8(2), just means multiplication, so it would look like this: 8×2.

Next, we do all the multiplication in our problem.

9+9×6÷3-2.

9×6=54.

Now our problem looks like this;

9+54÷3-2.

Next, we do the division.

9+54÷3-2

54÷3=18.

Now our problem looks like this;

9+18-2.

Next, we do the addition.

9+18-2

9+18=27

Now it looks like this;

27-2.

Finally, we subtract.

27-2=25.

Your final answer is 25!

Have a nice day! :)
