Given the following system of equation:

x - y = 10

3x - 2y = 25

Let's determine the solution by elimination:

a.)

x - y = 10

3x - 2y = 25

b.)

(x - y = 10)(-2)

3x - 2y = 25

c.)

-2x + 2y = -20

3x - 2y = 25

x + 0 = 5

x = 5

Therefore, x = 5

Next, let's find y.

Substitute x = 5 in x - y = 10

x - y = 10

5 - y = 10

-y = 10 - 5

-y = 5

-y/-1 = 5/-1

y = -5

Therefore, the solutions are: x = 5 and y = -5 or (5, -5)
