-5x-2y=2....(1)
6x-2y=24.....(2)
multiply (2) by -1,
-6x+2y=-24....(3)
add (1)+(3)
-5x-2y-6x+2y=2-24
-11x=-22
-11x/11=-22/11
x=2
plugging in the value of x in (1)
-5(2)-2y=2
-10-2y=2
addind 10 to both sides
-2y=12
deviding both sides by -2
y=-6
so (x,y)=(2,-6)
Answer:
there is no solution for the question
Answer:
$413.20
Step-by-step explanation:
40% of 772 is 308.8, so we take 772 and subtract 308.8. that equals 413.2, therefore the answer should be $413.20. comment part b and I’ll give you that answer too
When you divide 36.89/8.6, you get should $4.29 for 1 gallon of gas.
Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ± 
= ± 
= ± 2
