Add three to both sides
2x greater than 14 - 5x
Add 5x to both sides
7x greater than 14
divide both sides by 7
x is greater than 2

keep scrolling it is kind of long
Step-by-step explanation:
−2x+2y=−4,3x−2y=4
−2x+2y=−4for x:
−2x+2y=−4
−2x+2y+−2y=−4+−2y
−2x=−2y−4
-2x/-2=-2y-4/-2
x=y+2
Substitute y +2 for x in3x−2y=4:
3x−2y=4
3(y+2)−2y=4
y+6=4
y+6+−6=4+−6
y=−2
Substitute −2 for y in x=y+2:
x=y+2
x=−2+2
x=0
x=0 and y=−2
The price of the camera after the increase was $315 you multiply 450 by .50 and then you get 225 next you multiply 225 times .40 and you get 90 you then add 90 to 225 and you get 315
Answer:
Quiana has 8 text messages from Pierre.
Step-by-step explanation:
This question can be solved using a rule of three.
