Answer:y = 160
Step-by-step explanation:
The given equation is expressed as
-80 + y = 80
It is a linear equation with only one variable. The variable is y. The constants on the left hand side of the equation and the right hand side of the equation are - 80 and 80 respectively. To determine the value of the variable, y, we would eliminate the constant on the left hand side of the equation by adding 80 to the left hand side of the equation and the right hand side of the equation. It becomes
-80 + 80 + y = 80 + 80
0 + y = 160
y = 160
The answer is x^3 - 7x^2 + 5x + 21

I had x before the movie.
x - 13.50 = 26.50
Add 13.50 to both sides of the equation:
x = 40
I had $40 before the movie.

The original balance was x.
x - 161.15 = 423.28
Add 161.15 to both sides:
x = 584.43
The previous balance was $584.43
Answer:
p = q/5 - 9r/5
Step-by-step explanation:
Step 1: Write equation
5p + 9r = q
Step 2: Solve for <em>p</em>
<u>Subtract 9r on both sides:</u> 5p = q - 9r
<u>Divide both sides by 5:</u> p = q/5 - 9r/5
