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.
2x = 3x Cross multiplied
2x — 2x = 3x — 2x Added —2x to both sides
0 = x Collected terms
x = 0 Exchange terms
x = 0 This is the solution.
