Add 2 to both sides:

Divide both sides by -4 (this is negative, so we have to swap the inequality sign):

2

Expand the left hand side:

Add 8 and y to both sides:

Divide both sides by 3

3-4
Nothing different from 1 and 2, apply the same logic (expand sides, gather constant and non-constant terms together, solve for the variable) and you will solve them
The answer is 30.857142 = x
