So you want to make one of the equations equal to one of the placeholders exg y=x+3
so we have
x+y=2 and
-2x+y=2
I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x
subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0
subsitute x=0 in x+y=2
0+y=2
y=2
x=0
y=2
If this is a T/F question
then falseeeee
Answer: The answer is A and D
Step-by-step explanation: If you go through all the problems, just replace "b" with "(4)" into a calculator. For A and D, they both equaled 180.
If it the orginial price of the sweater is 75%, then 25% was taken off.
Turn 25% into a decimal.
.25
Multiply that by 27.
27*.25= 6.75
Add that to the discounted price.
27+6.75= 33.75
33.75 is your answer.
I hope this helped you.
Brainliest answer would be appreciated.
