Answer:
Explanation:
Okay. So let's say X.
That is the cost of one Taco and why? That is the cost of one drink. Right?
So it is given that three tacos including cost $13.
our first equation is three X plus two Y.
That is equal to $13. And it is also given that four Tacos and wondering cost $15.25.
our second equation is for x plus y is equal to $15.25.
Right now here we need to solve this equation for Y.
we can write why is it called do 15.25 -4 X.
Right now substitute the value of Why in this first equation now simplify this. So 15.25 multiply by two.
That is 13.5. What? X.
multiply by two.
That is eight x.
You're three X minus eight X.
That is minus five X. And 43 -30.5.
So that will be will do -17.5.
Right Now we need to do it both sides by -5.
Terefore X is equal to 3.5. Alrig
