I need a breakdown of how to solve for u. My mom and I have worked the problem and we've both gotten different answers. So i need someone to break down how they would sove it.

## Can someone please break down "2u-3=2(4-u)-3" solving for u

Remember "PEMDAS" for the order of operations.

First, parenthesis

second, exponents,

Third, multiply and divide.

Finally, add and subtract,

Hope this helps.

Good hearing from a fellow Virginian, Lee!

The "-3's" on both sides balance out ... 2u = 2(4-u) ... the "2's" balance out ... u= 4-u

... put minus elements "on the other side" ... u+u =4 ... sounds like 2+2 =4 ==> u=2

... Best wishes :)

Rusty has the right answer.

My approach is just a little different:

REMEMBER YOUR GOAL IN ANY PROBLEM: Get the variable alone on one side of the equal sign.

Step 1. Do the math according to the order of operations:

(Think: "

**P**lease**E**xcuse**M**y**D**ear**A**unt**S**ally")**P**arenthesis

**E**xponents

**M**ultiplication

**D**ivision

**A**ddition

**S**ubtraction

Step 2. Get U alone on one side of the equal sign by removing everything else from that side:

(

**Remember**: What you do to one side of the = sign, you must do to the other side as well, so you do not change the value)Step 3. Divide to Solve for U

1. Multiply: 2u - 3 =

**2(4 - u)**-3 2u - 3 = 8 - 2u - 3

2. Add: 2u - 3

**+ 3**= 8 - 2u - 3**+ 3** 2u = 8 - 2u

Add: 2u

**+ 2u**= 8 - 2u**+ 2u** 4u = 8

3: Divide: 4u =
8

**4**

**4**

u = 2

I need a breakdown of how to solve for u. My mom and I have worked the problem and we've both gotten different answers. So i need someone to break down how they would sove it.

### 2u-3=2(4-u)-3

First, distribute the 2 on the right side:

### 2(4-u) = 8 - 2

now it is

### 2u - 3 = 8 - 2u -3

Next, we can add 3 to each side. That leaves:

### 2u = 8 - 2u

Now, add 2u to each side:

### 4u = 8

### Finally divide each side by 4:

## u = 2

Hope this helps, and vote for me.
