3 possible solutions to the equation 2x+y=10 are shown below:
X= 3, Y=4
(3*2+4=10)
X= 1, Y=8
(1*2+8=10)
X=4, Y=2
(4*2+2=10)
Hope this helps! :)
Answer:
The correct answer is 333 1/ 3 ml 30% solution and 166 2/ 3 ml of 45% solution.
step-by-step explanation:
Set up 2 equations. Let x be the 30% solution and y be the 45% solution. Then you have x + y =500 and .3x +.45y = .35*500. Then solve the system.
When it doesn’t look like a U anymore and is upside down
Looking at an equation than when x is negative
