If you have a problem like:
4x+2y=20
2x+2y=16
You would subtract
4x-2y=20
-2x+2y=16
You would get the new problum
2x=4
You now want to divide the 2 on both sides to solve for x
x=2
Now that you've solved for X you want to solve for y. So use substitution to solve for y. You would want to substatute the x for the 2 in either of the problums. I'll use the first one.
4(2)+2y=20
You first want to multiply te 4(2) you would get a new problum.
8+2y=20
Now you want to subtract the 8 on both sides.
2y=12
The last step to solve for y is to divide the 2 on both sides.
Y=6
So your answers would be
x=2
y=6
Answer:6x - 2y = 22
Step-by-step explanation:
Just multiplying equation by 2
Can do it with any number
If you use the equation for Rachel it would be
y=3x and for oliver it would be y=2x+5
Answer:

Step-by-step explanation:
Answer:
32 dollars
Step-by-step explanation:
Let's say the original price is x
Create an equation:

The answer is 32 dollars
Hope this helps :)
Have a nice day!
