Answer :
Answer:
Step-by-step explanation:
The equation for Pablo's order is given as 6T+2D=9 or 6T+2D-9=0
While the equation for Jasmine's order is given as 4T+2D=7 or 4T+2D-7=0
Subtracting Jasmine's equation from Pablo's
6T+2D-9-(4T+2D-7)=0
This gives us
6T+2D-9-4T-2D+7=0
The reduces to
2T-2=0
Dividing all through by 2 gives
T-1=0
Therefore
T=1
Substituting the value for T into any of the equations of either Pablo and Jasmine
Using Pablo's
6T+2D=9
6(1)+2D=9
2D=9-6
2D=3
There D= 3/2
