Algebra Notes

Equation-mathematical statement with two expressions that have the same value eg.
x + 2 = 3
y - 7 = (-4)
3a - 2 = a + 2
b = 4
Here's an example of an equation we had to model

Model: 8 times a number plus 4 is 12

Answer: 8n + 4 = 12


Here's an equation we got and we had to identify, the variable, the numerical coefficient, an the constant

5y - 6 = 19

Variable- Y
Numercial Coefficient- 5
Constant- 6

Opposite Opperations ( /- means divide)

+ , -
x , /
- , +
/ , x

Here are examples of how to solve an algebra equation

After you find out what the variable is re-write it again
