Answer 1

Answer:

Step-by-step explanation:

1)3x-9=3

3x=3+9

3x=12

x=12/3

x=4

2)2(y-3) = 6

2y-6=6

2y=6+6

2y=12

y=12/2

y=6

3)y/2 + 3=5/2

(y+6)/2=5/2

2(y+6) = 5(2)

2y+12=10

2y=10-12

2y=-2

y=-2/2

y=-1

4)2y+1/2=3/2

2y=3/2-1/2

2y=2/2

2y=1

y=1/2

5)5x-7=2x+8

5x-2x=8+7

3x=15

x=15/3

x=5
