Substitution doesn't work for this, but elimination does.
-6x-8y=-20 +6( x+6y=-6)
-6x-8y=-20 + 6x+36y=-36
-6x and 6x cancel each other, add -8 and 36 to get 28, and -20 and -36 to get -56.
28y=-56
divide by 28 on both sides.
Y= -2
Then substitute y into one of the equations.
x+6(-2)=-6
x-12=-6
x=6
The ordered pair is (6,-2).
Answer:
the set of whole number since it is defined as positive integers + zero
71/60. You change the denominators(bottom numbers) to 60 because that is the smallest number that both 10 and 12 can go into. Then you just add.
Well you use PEMDAS (1. Parentheses 2. Exponents 3. Multiplication and Division in order from left to right 4. Addition and Subtraction in order from left to right) to solve. you have no parentheses or exponents so you do multiplication and division first 14*14 = 196, and 196/14 is 14. Then you do addition and subtraction. 14 + 14 = 28. 28 - 14 = 14.
Answer
Solution:
p = 79
n = 52
Step-by-step explanation:
Given equations:
A) 
B) 
To solve for 
and 
Naming the first equation as A and second as B.
Using elimination method to solve.
In order to eliminate we subtract equation A from B.
Subtracting A from B i.e [
(B)
- (A)
We get, 
Dividing both sides 2.26.
∴ 
We can solve for by substituting in equation A.
Subtracting both sides by 52.
∴
