Answer: X = 24
Step-by-step explanation:
Move all terms to the left:
(3x + 10) - (2x - 9) - 43 = 0
Get rid of all the parenthesis:
3x + 10 - 2x - 9 - 43 = 0
Add all the numbers and all variable:
x-24 = 0
Move all terms containing x to the left and all other terms to the right:
x = 24
Answer:
x^2+0x+(-x^2)=0
Explanation:
x^2+0x+(-x^2)=0
Anything multiplied by 0 is equal to 0
x^2+0+(-x^2)=0
x^2+(-x^2)=0
A positive and a negative makes a negative
x^2-x^2=0
0=0
For these types of problems, play around with multiplying by 0 and adding negatives.

b. 8 because Total Pieces Sold=60
Pieces contributed by the cafeteria=20
Pieces contributed by the clubs=x
We can solve this problem by creating an equation to relate these terms:
Total Pieces Sold= (pieces contributed by the cafeteria) + (pieces contributed by the clubs)
Our equation is therefore: 60=20+x. We solve for x:
60-20=x
40=x
This means the clubs contributed 40 pieces. To find out how many pies that equals, we can use the relationship:
(40 pieces)/(y pies) = (5 pieces)/(1 pie). Solve for y:
(1)(40)=(5)(x)
(40/5)=8
