I want help with this equation -1 + x = 8x - 8
Ilya [14]

Answer:

x=1

Step-by-step explanation:

To solve for x, we need to get x alone on one side of the equation.

Add one to each side of the equation.  Subtract 8x from each side of the equation.  Divide both sides by -7.  You should get 1 as the answer.

-1+x=8x-8\\x=8x-7\\-7x=-7\\x=1

Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15

Step 2: Divide the decrease by the original number

1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2

Step 3: Multiply the result by 100 to get a percent decrease

0.2 \times 100\\\\= 20

Therefore, the percent decrease of the price of paper per package is 20%

<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>
