Do what’s in the brackets first it should be 23/12 or 1 11/12 or 1.916
Three equations are:
2x+1=6x+3
8x+6=2x+3
8x+4=2x+1
<u>Step-by-step explanation:</u>
Using the digits 0-9, no more than one time each, place a digit in a box to create an equation with a solution x= -1/2 . We need to Create three equations. Formula is below. __ x+ __=__ x+ __ . Let's find out:
2x+1=6x+3
Let's verify this :
⇒ 
⇒ 
⇒ 
8x+6=2x+3
Let's verify this :
⇒ 
⇒ 
⇒ 
8x+4=2x+1
Let's verify this :
⇒ 
⇒ 
⇒ 
3x3/2=4.5cm
50/4.5cm = 11.111......
=11 can be made

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
4y² + 5y + 2 + 8y² + 4y + 5
<u>Step 2: Simplify</u>
- Combine like terms (y²): 12y² + 5y + 2 + 4y + 5
- Combine like terms (y): 12y² + 9y + 2 + 5
- Combine like terms: 12y² + 9y + 7
