Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
Since both expressions are equal to y, you have to equal both expressions like this:
Now you can solve the equation:
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result
So, the answer is x=10 and y=-1
Answer:
el 90% de 96 es 86.4 amigo
Answer:
And solving for x we got:
And replacing for x we got:
And for the cost would be:
Step-by-step explanation:
Assuming the following info corrected :Omar will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $59 and costs an additional 0.11 per mile driven. The second plan has an initial fee of $52 and costs an additional $0.15 per mile driven
For this case we know that the first plan has an initial fee of $59 and costs an additional 50.11 per mile driven and the second plan has an initial fee of $52 and costs an additional $0.15 per mile driven.
So we can set up the following equations for each cost
With c1 the cost of the plan 1 and x the number of miles
With c2 the cost of the plan 2 and x the number of miles
We can set equatl the two costs:
And replacing we got:
And solving for x we got:
And replacing for x we got:
And for the cost would be:
