x/2=2 /x
Use cross multiplication to
• determine the value(s) of x that will make the equation true, or
• determine that any value of x will make the equation true, or
• determine that any value of x, except zero, will make the equation true, or
• determine that no value of x will make the equation true.
x2=4 Cross multiplied
1(x2) = 44 Take square root of both sides
x = 2 Simplify radical
x = ±2 Account for negative root
x = ± 2 This is the solution.
