Answer:

z = 4

Step-by-step explanation:

18z = 72 (First divide by 18 to isolate z, the exponent)

Find the value of two numbers if their sum is 23 and their difference is 5

yKpoI14uk [10]

Let the two numbers be represented by x and y respectively.

Then x + y = 23, and x - y = 5.

Solve this system of linear equations for x and y. Start by rearranging them vertically:

x + y = 23

x - y = 5

--------------- Combining the two equations eliminates y:

2x = 28.

Then x = 14. If x = 14, then 14 + y = 23, and y = 9..

The solution is (14, 9); that is, x = 14 and y = 9.
