What is 2x-3 I have no idea what it is

Mathematics
1 answer:
cricket20 [7]3 years ago
7 0

Answer:

Step-by-step explanation:

2x - 3 is a linear expression.  y = 2x - 3 is the equation describing y.

If x = 1, y = 2(1) - 3 = -1

If x = 2, y = 2(2) - 3 = 1

and so on.

Isn't there more to this problem that merely "2x - 3"?

What is the solution to this system of equations?<br><br> -5.9x-3.7y=-2.1<br> 5.9x+3.7y=2.1
marin [14]

Answer:

There are infinite solutions that solve the system y=0.57-1.59x

Step-by-step explanation:

  • The solution can be expressed as y=0.57-1.59x (there are infinite solutions that solve the system). This results from rearranging terms in the first or second equation.
  • This is because the first equation is a linear combination of the second one (this is, the first equation equals (-1) times the second equation). This means that the second equation does not add any information about x and y: it says exactly the same as the first equation about the relationship between x and y.
  • Then, in terms of solving the system, you have one unique expression (not repeated) that shows the relationship between y and x. This means that, any pair of (x,y) that meet the requirements expressed by y=0.57-1.59x, will solve the system. Then we have infinite solutions.
