Dr. Bhatia mixes 2 liters of a 5% saline solution with x liters of a 90% saline solution. The table shows the amount of each solution used. What is the value of x?

pls refer ro the top for answer

ask the math teacher she or he would know lol.

step-by-step explanation:

i suppose it should be (y=2x-5)

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
