Solving multi-step problems using non-linear equations in one variable

 $\frac{4}{x-3}=\frac{5}{2x-3}$  
What is the value of x?

• 2

• 1

• -1

• -3

Solve for x

• 2/5
• 2
• 5/2
• 5

Solve for x

• 5

• 4/5

• 1

• - 4

What is the value of a in

 $\frac{3}{x^2-x}=\frac{1}{x}$  ?

How to avoid breaking the 1st Rule:

Solve for x

• x = 6

• x= $3\ \frac{3}{5}$

• x = $9\ \frac{1}{2}$

• x = -6

Solve by cross-multiplying

• x = 6
• x = -6
• x = 6/7
• x = -6/7

Solve by cross-multiplying.

• x = 2
• No Solution
• x = -10
• x = 10
