Need help getting stuck on this problem

Mathematics

Answer:

  • Variable x in first equation

Step-by-step explanation:

<u>Given system</u>

  • x = 5y - 1
  • x + 2y = 13

Variables in this system are x and y.

Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.

We see <u>variable x is isolated </u>in the first equation.

In the second equation both of the variables are on the same side so they are not isolated.

What are the solutions to the equation 0 = x2 – x – 6?
ioda
Factor to this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?). 
The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6. 
x - 3 = 0
x = 3
x + 2 = 0
x = -2
The two solutions are therefore, x = 3 and x = -2. 

Hope it helps
