Answer:
Well do you know the butterfly method
you multiply 2 by x+1 and 4 by x + 2
Step-by-step explanation:
2(x+1) + 4(x+2) = 3(x-3) -2(x - 1)
2x + 2 + 4x + 8 = 3x - 9 - 2x + 2
2x + 4x +8 = 3x - 2x -9 +2
6x + 8 = x -7
6x - x = -7 -8
5x = -15
x = -15/5
x = -3
Hey There!!
Your answer will be 3.
Step-by-step explanation:
Because, 2 + 1 = 3
Answer:
To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
Say the price of 1 apple is x and the price of 1 orange is y. Then, we can write the two equations:
4x + 4y = 10
6x + 6y = 15
We can try to solve this by elimination, which means getting rid of one variable so that we're left with only 1 variable to solve for. Multiply the top equation by 3 and the bottom equation by 2:
3 * (4x + 4y) = 10 * 3 ⇒ 12x + 12y = 30
2 * (6x + 6y) = 15 * 2 ⇒ 12x + 12y = 30
Subtract the bottom equation from the top:
12x + 12y = 30
- 12x + 12y = 30
______________
0 + 0 = 0
Since we result in 0 = 0, that means any values of x and y we put into the equations will work, so we cannot find a unique price.
Hope this helps!
2x*2=14x-20
<span>Simplifying
2x * 2 = 14x + -20
Reorder the terms for easier multiplication:
2 * 2x = 14x + -20
Multiply 2 * 2
4x = 14x + -20
Reorder the terms:
4x = -20 + 14x
Solving
4x = -20 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation.
4x + -14x = -20 + 14x + -14x
Combine like terms: 4x + -14x = -10x
-10x = -20 + 14x + -14x
Combine like terms: 14x + -14x = 0
-10x = -20 + 0
-10x = -20
Divide each side by '-10'.
x = 2
Simplifying
x = 2
Best of luck hope I helped :)
