Answer:
y = 1/2x - 9
General Formulas and Concepts:
<u>Alg I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Standard Form: 4x - 8y = 72
<u>Step 2: Find slope-intercept form</u>
- Subtract 4x on both sides: -8y = 72 - 4x
- Divide both sides by -8: y = -9 + 1/2x
- Rewrite: y = 1/2x - 9
Answer:
x=1
Step-by-step explanation:
4x+1=5
4x=5-1
4x=4
x=4/4=1
This happens to be a whole number.

Step-by-step explanation:
<span>9x + -4 = 77
Reorder the terms:
-4 + 9x = 77
Solving
-4 + 9x = 77
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 9x = 77 + 4
Combine like terms: -4 + 4 = 0
0 + 9x = 77 + 4
9x = 77 + 4
Combine like terms: 77 + 4 = 81
9x = 81
Divide each side by '9'.
x = 9
Simplifying
x = -9</span>
