Answer:
The solution is (2, 1).
All other ordered pairs do not work.
Step-by-step explanation:
-2x + 5y = 1
5x - 3y = 7
-10x + 25y = 5
10x - 6y = 14
19y = 19
y = 1
5x - 3(1) = 7
5x = 10
x = 2
(2, 1)
The solution is (2, 1).
All other ordered pairs do not work.
Hello!
The original equation is:
200 = (5w ÷ 2)8
This problem can be written as:
200 = (5w/2)8
And you can then reduce the numbers with 2:
200 = 5x * 4
200 = 20x
10 = x
Your correct answer is 10.
Answer:
16:8 2:1
Step-by-step explanation:
it's both 8 and 4 times 2 on each side, and then divided on each side
So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you <span>−2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on
but at the end you should get x=-1 and y =3
