-4/13y – 7=6

8a – 3+1.2a = 9

5f + 1/8 = -3 (Find the value of f)

p + 3/10 = 4 (Find the value of p)

• Math -

-4/13y-7=6
-4/13y=6+7
-4/13y=13
-4/13=13y
-4/(13*13)=y
-4/169=y

p+3/10=4
p+3/10=40/10
p=40/10-3/10
p=37/10
p=3.7

you can solve the other two in the same method, hope this helps!

• Math -

First, you want to get the numbers on one side and the terms containing the unknown on the other.

-4/13y – 7 = 6

-4/13y = 13

To get the y alone on one side, multiply both sides by -13/4.

y = 13(-13/4)

y = -169.4 or -42.25 or -42 1/4

I hope this makes the process clearer.
