1. First, we need to plug in the variables into the numbers from the information to create our first equation for the system. 3j (glasses of orange juice) + 5p (5 pancakes) = 7.60. Now, plug in the variables into the numbers from the information for the second equation for the system. j ( a glass of orange juice) + 2p ( 2 pancakes) = 2.90. 2. Now, we have the system of equation, 3j + 5p= 7.60 and j + 2p= 2.90. Our next step is to plug in j and use the substitution method by changing the j + 2p= 2.90 to -2p + 2.90. Then, we plug this into our first equation. 3(-2p + 2.90) + 5p = 7.60. Now, we use the distributive property. 3 x -2= 6 and 3 x 2.90= 8.70. Now, we have 8.70 – 6p + 5p= 7.60. Then, we combine the like terms in the equation, which
