2x = 19

x = 9.5.

Hope this helps!

Answer 2

Explanation:

1).

2x + 6 = 12

Send the constant to the right side of the equation

That's

2x = 12 - 6

2x = 6

Divide both sides by 2

x = 3

2).

5x - 15 = 3x + 4

Group like terms

We have

5x - 3x = 15 + 4

Simplify

2x = 19

Divide both sides by 2

x = 19/2

Hope this helps you
