Multiply the bracket by -2
2x+3y^2 -2(x-y2)
2x+3y^2-2x+2y^2
2x-2x+3y^2+2y^2- rearranging
3y^2+2y^2
5y^2
Answer: 5y^2
Answer:
12 cups
Step-by-step explanation:
Y = mx + b format
2y = 6x - 10
y = 3x - 5
Let
x---------> the number
we know that
[9+2x]*4=4x+12
36+8x=4x+12
8x-4x=12-36
4x=-24
x=-24/4
x=-6
the answer is
-6
To solve a problem like this, you can use a method called cross-multiplying. This is when you multiply the denominator of the first fraction by the numerator of the other and then multiply the two remaining numbers.
![\frac{x}{4} = \frac{6}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B4%7D%20%3D%20%5Cfrac%7B6%7D%7B12%7D%20)
To make this easier on yourself, simplify first!
![\frac{x}{4} = \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B4%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20)
Multiply x by 2 and multiply 4 by 1.
2x = 4 Divide both sides by 2.
x = 2
You can check this by comparing the fractions with 2 in the place of x.
![\frac{2}{4} = \frac{6}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B4%7D%20%3D%20%5Cfrac%7B6%7D%7B12%7D%20)
Simplify!
![\frac{1}{2} = \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20)
The fractions are equal, so
x = 2 .
