Answer:
(2,-3)
Step-by-step explanation:
2x + 2y = -2
3x - 2y = 12
Add the two equations to eliminate y
2x + 2y = -2
3x - 2y = 12
-----------------------
5x = 10
5x/5 = 10/5
x = 2
Now find y
2x+2y = -2
2(2)+2y = -2
4+2y = -2
Subtract 4 from each side
4-4 +2y = -2-4
2y = -6
Divide by 2
2y/2 = -6/2
y = -3
(2,-3)
Answer:
Step-by-step explanation:This is an improper fraction: 243/10 to convert it to a mixed number just do 243 divided by 10 which equals 24, so put that number as a whole number in front of the fraction, then do 24 times 10 which equals 240, then since 240 is 3 less than 243 the answer is 24 and 3/10.
If you need, I can try to explain it better.
Answer:
2x=180-(3x+20)
2x=180-3x-20
5x=160
x=32
