General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
13x - 6y = 22
x = y + 6
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: 13(y + 6) - 6y = 22
- Distribute 13: 13y + 78 - 6y = 22
- Combine like terms: 7y + 78 = 22
- Isolate <em>y</em> term: 7y = -56
- Isolate <em>y</em>: y = -8
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x = y + 6
- Substitute in <em>y</em>: x = -8 + 6
- Add: x = -2
0.55 is equal to 55/100, and by dividing the numerator and denominator by 5, we get 11/20. Hope this helps!
81x - 126x ÷ 3x + 1
45x / 3x + 1
15x / x + 1
2.25
Hope that helps you out
The answer to the question is x=-12.1hopes this helps you.
<span> Step 1: subtract X from both sides.
0.5x-6-x=x+0.05-x
-0.5x-6=0.05</span>
Step 2: Add 6 to both sides.
-0.5x-6+6=0.05+6
-0.5x=6.05
Step 3: Divide both sides by -0.5.−0.5x−0.5=6.05−0.5
