Respuesta :
For this case we must find the number of marbles that Jennifer has.
Let T be the variable that determines the number of total marbles that Jennifer has.
Let x be the variable that represents the number of red marbles that Jennifer has. So, [tex]x = 7[/tex]
Let y, the variable that represents the number of marbles blues Jennifer has. So, [tex]y = 7[/tex]
To find the value of T, we must add the variables x and y.
So, [tex]T = x + y[/tex]
[tex]T = x + y[/tex]
[tex]T = 7 + 7\\T = 14[/tex]
So, Jennifer has 14 marbles.
Answer:
14 marbles
