General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-9 = 2(18) + 9y
<u>Step 2: Solve for </u><em><u>y</u></em>
- Multiply: -9 = 36 + 9y
- Subtract 36 on both sides: -45 = 9y
- Divide both sides by 9: -5 = y
- Rewrite: y = -5
<u>Step 3: Check</u>
<em>Plug in y to verify it's a solution.</em>
- Substitute: -9 = 2(18) + 9(-5)
- Multiply: -9 = 36 - 45
- Subtract: -9 = -9
Answer:
one solution
Step-by-step explanation:
X-9=0
Add 9 to each side
X-9+9=0+9
x = 9
There is one solution
