Sign In
In the given diamond, y is - 1. We can fill the remaining corners when we find a number corresponding to x such that the product xy is equal to 6.
xy= 6 ⇒ x (- 1)=6
Notice that we got an equation that we can solve for x. Let's do it!
.LHS /- 1.=.RHS /- 1.
a(- b)=- a * b
Put minus sign in front of fraction
a/1=a
- (- a)=a
We found that x is equal to - 6. Now we can calculate the value of the sum x+y.
Finally, we can complete our Diamond Problem.
In the given diagram, x has a value of 3. We also know that the sum x+y is equal to - 5. Let's use this information to find the value of y.
x= 3
LHS-3=RHS-3
3-3=0
a-b = a+(- b)
Add terms
We found that y is equal to - 8. Next, we can calculate the value of the product xy.
Now we can complete our Diamond Problem.
In the given diagram, x has a value of 1.2, and the sum x+y is equal to 11.2. With this in mind, let's find the value of y.
x= 1.2
LHS-1.2=RHS-1.2
Subtract terms
We found that y is 10. Next, let's calculate the value of the product xy.
Now we can complete our Diamond Problem.
| Product (xy) | Sum (x+y) | Is Sum Equal to 10? |
|---|---|---|
| 24=1(24) | 1+24=25 | * |
| 24=2(12) | 2+12=14 | * |
| 24=3(8) | 3+8=11 | * |
| 24=4(6) | 4+6=10 | ✓ |
Notice that 4 and 6 are the numbers for which the product is 24 and the sum is 10. We can use this information to fill our Diamond Problem.
Remember that this is one of the possible solutions. The Diamond Problem for x=6 and y=4 also corresponds to the pattern.
