For example, if you obtain that z₁ = 1-2x2 + 3x3 where 2 and 3 are free, then as the value of a you should enter 1 2*x 2 + 3*x 3. Use the underscore to indicate subscripts of variables, and to indicate multiplication. • If a variable is a free variable, enter the variable name as its value. For example, if x₂ is a free variable, then you should enter x 2 as the value of ₂- . If the system has no solutions enter None as the value of one of the variables. In such case you can leave values of the remaining variables blank. I -122-5-x-2 -21 +2₂-23 = 3 -321 +4x2+3+4=10 4x16x2 - 4x32x4 = -14 x3 = X4=

Expert Solution
Step 1: Write the system of equations

Given space that space the space system space of space equations space
minus x subscript 1 plus x subscript 2 minus x subscript 3 equals 3
minus 3 x subscript 1 plus 4 x subscript 2 plus x subscript 3 plus x subscript 4 equals 10
4 x subscript 1 minus 6 x subscript 2 minus 4 x subscript 3 minus 2 x subscript 4 equals negative 14
This space is space in space the space form space A x equals b
Here space space A equals open square brackets table row cell negative 1 end cell 1 cell negative 1 end cell 0 row cell negative 3 end cell 4 1 1 row 4 cell negative 6 end cell cell negative 4 end cell cell negative 2 end cell end table close square brackets space space comma space space x equals open square brackets table row cell x subscript 1 end cell row cell x subscript 2 end cell row cell x subscript 3 end cell row cell x subscript 4 end cell end table close square brackets space space comma space space b equals open square brackets table row 3 row 10 row cell negative 14 end cell end table close square brackets space
