Answer: Lorena weighs 51 lbs more than Omar.
Step-by-step explanation: Set 4x+3 equal to 67, Lorena's weight. This makes sense because the x in 4x+3 represents Omar's weight.
4x+3=67
4x=64
x=16
The question asks for the difference between Omar and Lorena's weight, so simply subtract the two numbers.
67-16=51
