The system of equations may have a unique solution, an infinite number of solutions, or no solution. use matrices to find the general solution of the system, if a solution exists. (if there is no solution, enter no solution. if there are infinitely many solutions, express your answers in terms of z as in example 3.) 5x + 4y + 5z = −1 x + y + 2z = 1 2x + y − z = −3

Infinite number of solutions.

Step-by-step explanation:

We are given system of equations

Firs we find determinant of system of equations

Let a matrix A= and B=

Determinant of given system of equation is zero therefore, the general solution of system of equation is many solution or no solution.

We are finding rank of matrix

Rank of matrix A and B are equal.Therefore, matrix A has infinite number of solutions.

Therefore, rank of matrix is equal to rank of B.

step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
