Find the point of intersection of the lines x-3 = 0 and y-5 = 0. ​
Vikki [24]

Answer:

x = 3 and y = 5

Step-by-step explanation:

Given equations are :

x-3 = 0 ....(1)

y-5 = 0 ....(2)

We need to find the point of intersection of the lines.

Add 3 both sides in equation (1).

x-3+3=3

x = 3

Now, add 5 to both sides of the equation.

y-5+5=0+5

y = 5

Hence, the required point of intersection of the lines is x = 3 and y = 5.

Now we will dive the amount by the total number of seconds, we get

\frac{2,800,000,000,000}{31536000} =88787.41755 dollar
