0, equals, 7, y, minus, 5, x, minus, 8
0=
7y−5x−8
8, y, equals, 2
8y=
2

1 answer

To write the augmented matrix for the given system of equations, we first need to express the equations in standard form. The equations given are:

  1. \( 0 = 7y - 5x - 8 \)
  2. \( 8y = 2 \)

Let's rearrange these equations into standard form \( Ax + By = C \):

  1. Rearranging \( 0 = 7y - 5x - 8 \): \[ 5x - 7y + 8 = 0 \quad \Rightarrow \quad 5x - 7y = -8 \]

  2. Rearranging \( 8y = 2 \): \[ 0x + 8y = 2 \]

Now, we can write the augmented matrix for the system of equations: \[ \begin{bmatrix} 5 & -7 & | & -8 \ 0 & 8 & | & 2 \end{bmatrix} \]

This matrix represents the system of equations: \[ \begin{aligned} 5x - 7y &= -8 \ 0x + 8y &= 2 \end{aligned} \]
