Answer 2

To solve this system of linear equations, you can use the method of substitution or elimination. I'll use the elimination method here.

The system of equations is:

1. 1.5x - 1.15 = 1.1
2. 2.5x - 3.15 = 2.1

First, let's simplify both equations by adding 1.15 to both sides of the first equation and 3.15 to both sides of the second equation:

1. 1.5x = 1.1 + 1.15
2. 2.5x = 2.1 + 3.15

Now, calculate the values on the right side:

1. 1.5x = 2.25
2. 2.5x = 5.25

Now, we'll isolate x in each equation:

1. Divide both sides of the first equation by 1.5:

   (1.5x) / 1.5 = 2.25 / 1.5

   x = 1.5

2. Divide both sides of the second equation by 2.5:

   (2.5x) / 2.5 = 5.25 / 2.5

   x = 2.1

So, the solution to the system of equations is x = 1.5 and x = 2.1. This means that there are two possible values for x that satisfy both equations.
