Question 242070
To solve for y means to isolate y on one side of the equation.

x + 8y = 24

8y = -x + 24

y = (-x + 24)/8

y = (-1/8)(x) + 3


==========================================

The same rule applies here.  We isolate w.


4(4 - t) = 1 + w - 4

16 - 4t = w - 3

16 + 3 - 4t = w

19 - 4t = w
