The answer is (2,0)
Explanation
So I’m gonna use substitution to help me solve this problem. I’m gonna solve for x.
X-y=2
+y. +y
X= y + 2
Now that we have solved for x we are going to plug it into the first equation!
Shown like this
Y+2 - 10y = 2
Then we solve it as a normal problem
So first we combine light terms
-9y+2=2
Then we isolate the variable
-9y+2=2
-2. -2
-9y = 0
Then we divide by -9 on both sides
-9y /-9 = 0 / -9
Y = 0
Now that we solved for y we plug it into one the equations to get the x value!
X - 0 = 2
X=2
The solution is (2,0)
I hope this helped you! Pls mark as brainliest
Answer:
5
Step-by-step explanation:
Use PEMDAS to complete the problem
PE doesn't matter, there's not parentheses or exponents
MD=Multiplication and Division. Do 3*6=9, now your problem looks like 9-4
AS=Addition and Subtraction. 9-4=5
29.98+ 6.44 = 36.42 (cost with out the discount)
36.42/3 = 12.14
Answer-
12.14
First you simplify both sides
Multiply -1 by x and 7
-x-7-16=x-3
Subtract -16 from -7
-x+9=x-3
Add 3. To both sides
-x+12=x
Add x to both sides
12=2x
Divide both sides by 2
6=x
An independent variable is the variable that can be changed whilst the dependant variable cannot be changed to keep a fair test ✅
