An equation is shown below:
Dahasolnce [82]
Part A: first multiply 2 by x and -3, then combine the like terms, after that add 6 from both sides, then subtract 6x from both side, the answer is -5.
 4x + 2(x-3) = 4x + 2x - 11
          4x +2x -6 = 4x + 2x - 11
           6x -6 = 6x - 11
           6x = 6x -11 +6
         6x = 6x -5
          6x-6x= -5 
         0 = -5 
 part B) add the like terms

Use cramers rule to solve each system of equations :
Snowcat [4.5K]

Answer:

just follow the rules

Step-by-step explanation:

Cramer's rule applies to the case where the coefficient determinant is nonzero. ... A simple example where all determinants vanish (equal zero) but the system is still incompatible is the 3×3 system x+y+z=1, x+y+z=2, x+y+z=3.

Write the system as a matrix equation. ...

Create the inverse of the coefficient matrix out of the matrix equation. ...

Multiply the inverse of the coefficient matrix in the front on both sides of the equation. ...

Cancel the matrix on the left and multiply the matrices on the right.
