Consider that x = apples and y = cupcakes. If Janice has 4 apples, how many cupcakes will this have using this equation? 4x + 2y = 24
Solving for y knowing that x = 4. 4x + 2y = 24 4(4) + 2y = 24 16 + 2y = 24 Then subtract 16 from both sides. 2y = 8 Divide both sides by the 2. y = 4 Janice has 4 apples.
