4 / 3x= 8 / 6x
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.
24x = 24x Cross multiplied
x = x Divided both sides by 24
Any value of x, except 0, will satisfy the equation. Note: Zero must be excluded because x appears in the
denominator of the ratio and division by zero is
forbidden.
