Question

Need help getting stuck on this problem

Answer 1

Answer:

• Variable x in first equation

Step-by-step explanation:

Given system

• 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 variable x is isolated in the first equation.

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