Answer:
(7, -3)
Step-by-step explanation:
Add the two equations to eliminate x:
7y = -21
Then solve 7y = −21 for y:
= 
(<em>Divide both sides by 7)</em>
y = -3
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2y - 3x = -27
Substitute -3 for y in 3y - 3x = -27:
(2)(-3) - 3x = -27
-3x - 6 = -27 (<em>Simplify both sides of the equation</em>)
-3x - 6x + 6x = -27 + 6 (<em>Add 6 to both sides</em>)
-3x = -21
= 
(<em>Divide both sides by -3</em>)
x = 7
Answer:
70
Step-by-step explanation:
Answer: x = -0.3
Step-by-step explanation:
<u>Given expression</u>
1 - 3 (9x + 3) = 3x + 1
<u>Expand parentheses and apply the distributive property</u>
1 - 27x - 9 = 3x + 1
<u>Combine like terms</u>
(1 - 9) - 27x = 3x + 1
-8 - 27x = 3x + 1
<u>Subtract 3x on both sides</u>
-8 - 27x - 3x = 3x + 1 - 3x
-8 - 30x = 1
<u>Add 8 on both sides</u>
-8 - 30x + 8 = 1 + 8
-30x = 9
<u>Divide - 30 on both sides</u>
(-30)x / (-30) = 9 / (-30)
(-30)x / (-30) = 3 / (-10)
Hope this helps!! :)

Line graphs allow us to see overall trends such as an increase or decrease in data over time. Bar graphs are used to compare facts. The bars provide a visual display for comparing quantities in different categories or groups. ... Circle Graphs are used to compare the parts of a whole.
The answer is B, -12p² - 12pq + 2p - 3q² + q. You have to distribute each term using FOIL, which is First, Outside, Inside, and Last. Then you have to combine like terms and order the variable correctly.
