Problem N 2

we have

12x-14=8x+16

solve for x

subtract 8x both sides

12x-14-8x=8x+16-8x

4x-14=16

Adds 14 both sides

4x-14+14=16+14

4x=30

divide by 4 both sides

x=30/4

x=7.5

Problem N 4

we have

12x-14=6x+16

solve for x

subtract 6x both sides

12x-14-6x=6x+16-6x

6x-14=16

adds 14 both sides

6x=16+14

6x=30

divide by 6 both sides

x=30/6

x=5
