Answer:
The equations are:
[tex]T = 2Y[/tex] and [tex]T + 2Y = 15[/tex]
Step-by-step explanation:
Given
Represent bones eaten Today with T and yesterday with Y
Required
Write the equation
In the first statement, we have that:
[tex]T = 2Y[/tex]
Reading further; In the second statement
[tex]T + 2Y = 15[/tex]
Hence, the equations are:
[tex]T = 2Y[/tex] and [tex]T + 2Y = 15[/tex]
Solving further:
Substitute 2Y for T in the second equation
[tex]2Y + 2Y = 15[/tex]
[tex]4Y = 15[/tex]
Divide both sides by 4
[tex]Y = \frac{15}{4}[/tex]
[tex]Y = 3.75[/tex]
Recall that
[tex]T = 2Y[/tex]
[tex]T= 2 * 3.75[/tex]
[tex]T= 7.5[/tex]
