Answer:
The unique solution to the system is (x,y){(-9,-3)}
Step-by-step explanation:
x - y = -6 equation 1
5x + 6y = -63 equation 2
We will find the value of x from equation 1.
x= y-6
Now put the value of x in equation 2.
5(y-6)+6y = -63
5y-30+6y = -63
Combine the like terms:
5y+6y= -63+30
11y = -33
Divide both sides by 11.
11y/11 = -33/11
y = -3
Now put the value y = -3 in x=y-6
x = y-6
x= -3-6
x= -9
Therefore The unique solution to the system is (x,y){(-9,-3)} ....

Tammy’s bush would have 30 blooms. 80% of 30 is 24.
Answer:
The answer would be 16b^2 - 14b + 3
Step-by-step explanation:
In order to find this, we simply need to group the terms by their variable values. We will start with the b^2 terms.
5b^2 + 24b^2 - 13b^2 = 16b^2
Now we can use all of the b terms.
-5b - 8b - b = -14b
And finally, we'll do all the constants.
4 - 1 = 3
Using all three of these together will give us the simplified form.
