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.
x/4 =2x/ 8
8x = 8x Cross multiplied
8x/8=8x/8 Divided both sides by 8
x = x
Any value of x will satisfy the equation
