-2x + 8. you multiply all the terms inside the parenthesis by the one outside of/attached to them. the reason it is +8 and not -8 is because the negatives cancel out to give you a positive.
<em>Answer:</em>
<em>x = 21/4</em>
<em>x = 5 1/4</em>
<em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>- 3/4 = x - 6</em>
<em>- 3 = 4(x - 6)</em>
<em>- 3 = 4x - 24</em>
<em>4x = 24 - 3</em>
<em>4x = 21</em>
<em>x = 21/4</em>
<em>x = 5 1/4</em>
<em>Good luck !</em>

Answer:
$3100 is invested at 9%
$4900 is invested at 11%
Step-by-step explanation:
Let's take "x" be the amount invested at 9%.
(x + 1800) is invested in another account at 11%.
The interest amount earned by the two accounts is $818.
Here we can use the simple interest formula and find the amount invested in each account.
Simple interest (I) = , where P- is the principal , N is the number of years and R is the interest rate.
Simple interest =
0.09x + 0.11(x+1800) = 818
Now we have to simplify and find the value of x .
Use the distributive property and simplify the second term.
0.09x + 0.11x + 198 = 818
0.2x + 198 = 818
0.2x =818 - 198
0.2x = 620
x = 620/0.2
x = 3100.
So $3100 is invested at 9%
x + 1800 = 3100 + 1800
= $4900
$4900 is invested at 11%
Hope this helped.
