10x = -80 + 20

10x = -60

x = -60 / 10

x = -6

Answer 2

Let's solve the system of equations step by step:

1. 2x - 10 = 2x + 2

In this equation, you have 2x on both sides of the equation. When you subtract 2x from both sides, it cancels out:

2x - 2x - 10 = 2x - 2x + 2

This simplifies to:

-10 = 2

However, this equation is inconsistent because -10 does not equal 2. Therefore, there is no solution to this part of the system of equations.

2. 10x - 20 = -80

In this equation, you can start by adding 20 to both sides:

10x - 20 + 20 = -80 + 20

This simplifies to:

10x = -60

Now, divide both sides by 10 to solve for x:

(10x) / 10 = (-60) / 10

This simplifies to:

x = -6

So, the solution to the second equation is x = -6.

However, since the first equation is inconsistent, there is no solution for that part of the system.

In summary, the system of equations has no solution because the two equations are contradictory.
