First lets solve for a:

3a - 2b + 7 = 4a + 10
-3a               -3a

-2b + 7 = a + 10
      -10        -10
-2b -3  = a


Now, b:

3a - 2b + 7 = 4a + 10
-3a               -3a

-2b + 7 = a + 10
       -7        -7
-2b = a + 3
b = (a + 3)/-2

Hope this helps!

Let's do the simplest one here.

f(x) or y = x - 1

f(x) or y = x + 1

f(x) or y = -x

Wait, would this count as a solution? : See the second attachment
