Answer:
x=12 y=9
Step-by-step explanation:
first we need to do this equation to get X
we don't have y so y=0
x-(0)=12
we eliminate the 0
x=12
now, we have X, now we need to find Y
substitution
x+y=3
12+y=3
y=3-12
y= 9
Answer: x=-6
Step-by-step explanation:
Add 5 to both sides to get 2x by itself
Yes, subtract 1 from both sides to get 3x by itself so you can subtract 2x as to not get a negative x value
One common mistake would be to accidentaly adding or subtracting 1 or 5 when they are supposed to be added/subtracted. To avoid this just go back and check your awnser by plugging it in.
