Again Solve for these equation..THNKS :)?

Question

1) x-2y=1 (SOLVE FOR y)

2) 2/3y + a = a+b (SOLVE FOR Y)

3) x+5=2y-6 (SOLVE FOR x)

4)1/4x=3y+3 ( SOLVE FOR x)

5) 5x-9=2/3y (SOLVE FOR y)

Answer 1

1)

x - 2y = 1

2y = x - 1

y = (x - 1)/2

2)

2/3(y) + a = a + b

2y/3 = a - a + b

2y/3 = b

2y = 3b

y = 3b/2

3)

x + 5 = 2y - 6

x = 2y - 6 - 5

x = 2y - 11

4)

1/4(x) = 3y + 3

x/4 = 3y + 3

x = 4(3y + 3)

x = 4*3y + 4*3

x = 12y + 12

5)

5x - 9 = 2/3(y)

2y/3 = 5x - 9

2y = 3(5x - 9)

y = (15x - 27)/2

Answer 2

i will do a few to get you started..

x-2y=1

isolate y on one side:

-2y=1-x

divide through by -2:

y=x/2-1/2

2/3 y +a=a+b

2/3 y =b

y=3b/2

Answer 3

1) y = (x-1) / 2

2) y = (3/2)b

3) x = 2y - 11

4) x = 12y + 12

5) y = (15x-27) / 2

You should use more parentheses.  Some of those were ambiguous, but I gave you the benefit of the doubt.

Answer 4

1) y = (x-1)/2

2) y = 3b/2

3) x = 2y-11

4) x = 12y+12

5) y = (15x-27)/2

Answer 5

remember to treat both sides equally

x-2y =1       add 2y

x = 1+ 2y    subtract 1

x-1 = 2y   divide by 2

(x-1) /2 = y

2/3 y +a = a + b     subtract a

2/3 y = b               multiply by 3y

2=   3by              divide by 3b

2/3b = y        

that should get you started
