Identify which expressions or variables you are given in the diamond.
Comparing this diamond to the one showing the pattern, we can create two equations.
y=& -1
x+y=& 10
Since we know that y=-1, we can substitute it in the second equation to find x.
Since we know that x=11, we can find the upper square of the diamond by substituting x=11 and y=-1 in the expression xy.
Now we can complete our diamond!
In this diamond we have been given the values of x and y.
&x= 5
&y= -3
With the given information we can create the following equations.
x=& 23
xy=& 1
To complete the diamond we should substitute x= 23 in the second equation and find y.
Having found y, we can determine the last square in the diamond by substituting x and y in x+y.
Finally, we can complete our diamond!
For the last diamond we can create the following equations.
xy=& -14
x+y=& -5
This tells us that x and y, when multiplied, must give us a negative number. Therefore, either x or y must be negative and the other one must be positive. We have two cases that both results in a product of -14 when multiplied.
