Add 2y to both sides

12x-2y+2y= 8+2y

12x = 2y+8

Divide both sides by 12

12x/12 = (2y+8)/12

x= 1/6 y + 2/3

I hope that's help !

Answer:

Part 1)

Part 2)

Part 3)

Part 4)

Part 5)

Part 6)

Step-by-step explanation:

Part 1)

Multiply by -1 both sides

The solution is the interval -------> [-1.817,∞)

The solution in the attached figure N 1

Part 2)

rewrite

Multiply by -1 both sides

The solution is the interval--------> (0.09,∞)

The solution in the attached figure N 2

Part 3)

combine like terms

Adds 8 both sides

The solution is the interval--------> (-∞,6]

The solution in the attached figure N 3

Part 4)

Adds 5 both sides

Multiply by -1 both sides

Divide by 2 both sides

The solution is the interval--------> (-7,∞)

The solution in the attached figure N 4

Part 5)

applying distributive property left side

Subtract 14 both sides

Divide by 7 both sides

The solution is the interval--------> (-∞,-13)

The solution in the attached figure N 5

Part 6)

applying distributive property left side

Adds 117 both sides

Divide by -1 both sides

Divide by 13 both sides

The solution is the interval--------> [-9.31,∞) Answer:
