Answer:

x = 1

y = -2

z = -3

Explanation:

Okay, let's solve this system of equations:

3x + y + 2z = -10

x + 5y - 2z = -12

-2x + 3y = -1

To find x, y and z, we can use substitution.

Substituting the third equation into the first equation:

3x + y + 2z = -10

-2x + 3y = -1

-> x = 1

Substituting x = 1 into the second equation:

1 + 5y - 2z = -12

-> 5y - 2z = -13

-> 5y = -11 (subtracting -2z from both sides)

-> y = -11/5 = -2

Substituting x = 1 and y = -2 into the first equation:

3(1) - 2 + 2z = -10

-> 2z = -7

-> z = -7/2 = -3

Therefore, the solution is:

x = 1

y = -2

z = -3
