You solved a linear system with two equations and two variables and got the equation -6=-6. how many solutions does the systems of equations have?

The system of equations will have an infinite number of solutions.

Step-by-step explanation:

i) when we arrive at a solution of a linear system with two equations and two

 variables and the solution of the equation does not give the value of any

 variable but rather is in the form of an identity like the one given, that is

 -6 = -6, then we can say that the two equations are exactly the same and

  that the system of equations will have an infinite number of solutions.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
