If Jake loses 33 pounds, he will weigh twice as much as his sister. Together they now weigh 153 pounds. What is Jake's present weight, in pounds?	Choose the most appropriate option:  A) 131  B) 135  C) 113  D) 147  E) 188
J = Jake’s current weight, in pounds   S = Sister’s current weight, in pounds   We are told that “If Jake loses 8 pounds, he will weigh twice as much as his sister.We put this into an equation:   J – 33 = 2S   J = 2S + 33 (Equation 1)   Next, we are told that “Together they now weigh 153 pounds.” We can also put this into an equation.   J + S = 153 (Equation 2)   To solve this equation, we can substitute 2S + 8 from Equation 1 for the variable J in Equation 2:   2S + 33 = 153-S   3S = 120   S = 40   J + 40 = 153   J = 113   Answer: 113
