At a Glance - Solving More Complex Equations

This multi-step business is not at all more complicated than what you've already been doing. It just involves three or more of the same kinds of steps.

Again, it is probably best to isolate the variable by first getting rid of the numbers least attached to the variable.

Example 1

Solve for x:

(2x + 6)/4 = -1


Example 2

Solve for x:

2x + 6x -2 = -34


Example 3

Solve for y:

-14/(y-2) = -10


Exercise 1

Solve for k:  (-k+8)/15 = 2


Exercise 2

Solve for w:  6w - 9 + 11w = 127


Exercise 3

Solve for x:  (37 - 12)/(x+1) = 5
