What is the solution to the system of equations. 2x-y=7 y=2x+3

1 answer:

8 0

To solve this, you can substitute the second equation into the first.

It becomes 2x-(2x+3)=7

Solve from here!

You get -3=7. Not possible. Therefore there is no solution to this system.

System is inconsistent. Hope this helps.

3. Define a variable, write an equation, and solve the problem. Carla began a

faust18 [17]

Answer:

Carla has been running 7 miles each day for 13 days.

Step-by-step explanation:

Carla ran 3 miles on her first day, 5 miles on her second day and then 7 miles each day onward.

Let the number of days she ran 7 miles each day = x

Total distance run by Carla = 3 + 5 + 7(x)

= 8 + 7x

If her log book shows that she has run total distance = 99 miles

Equation representing her total run will be,

8 + 7x = 99

7x = 99 - 8

7x = 91

x = $\frac{91}{7}$

x = 13 days

Therefore, Carla has been running 7 miles each day for 13 days.
