The 2 equations are
-2x + y = -17 ---1)
3x + y = 23 ---2)
we need to have the same coefficient for one of the variables.
Already y variable has the coefficient of 1 for both equations so we can use the equations as it is.
2) - 1) subtract 1) from 2)
3x-(-2x) + y -y = 23-(-17)
5x = 40
x = 8
substituting x = 8 in the 2nd equation
3*8 + y = 23
24 + y = 23
y = -1
solution - (8,-1)
total volume of the glass is .
<u>Step-by-step explanation:</u>
Here we have , A glass is 1/4 full. Then 70cm3 of orange juice is poured in.
The glass is now 3/5 full. We need to find that What is the total volume of the glass . Let's find out :
Suppose that volume of glass is x ,so according to question we have the following equation
, Now, solve this to find value of x
⇒
⇒
⇒
⇒

$266,260 would be by adding all three year salaries together . Now let’s divide that number by 3 to get an average 88753.33 now timed by 1.26% =$1118.29
The answer is $1118.29
