X = Juan's age
y = Eliza's age
Some key words/phrases we can use to help us make the equation are:
-is (whatever comes after this word usually equals the end result, or what it equals)
-two years younger
-than
-half her brother's age
.
just break it down :)
x/2 (half her brother's age) - 2 (two years younger) = y (Eliza is...)
| basically,
v
x/2 - 2 = y
So if Juan is 6, then we need to plug in 6 for x.
6/2 - 2 = y
3 - 2 = y
1 = y

General Formulas and Concepts:

- 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>
-5x - y = 12
y = -4x - 9
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -5x - (-4x - 9) = 12
- Distribute negative: -5x + 4x + 9 = 12
- Combine like terms: -x + 9 = 12
- Subtract 9 on both sides: -x = 3
- Divide -1 on both sides: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = -4x - 9
- Substitute in <em>x</em>: y = -4(-3) - 9
- Multiply: y = 12 - 9
- Subtract: y = 3
