Answer 1

By solving the given linear equation we conclude that x = -1

How to solve the linear equation?

Here we have the linear equation:

2x + 30 = -4*(5x - 2)

And we should solve this for x.

To do that we can start by expanding the right side, we will get:

2x + 30 = -20x + 8

Now we group like terms:

2x + 20x = 8 - 30

22x = -22

Now we divide both sides by 22:

22x/22 = -22/22

x = -1

So, we conclude that x = -1, as we wanted to prove.
