–3 /x=-2 /3
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 = – 9 Cross multiplied
–2x/– 2— 9 1-2 Divided both sides by –2
x=9/2 Reduced fraction
x = 41 Expressed as proper fraction
x= 41 This is the solution.
