Paso 1.1

Resta $100 x$ de ambos lados de la ecuación.

$C - 100 x = 200$

$R = 120 x$

Paso 1.2

Resta $120 x$ de ambos lados de la ecuación.

$C - 100 x = 200$

$R - 120 x = 0$

$C - 100 x = 200$

$R - 120 x = 0$

Paso 2

Write the system as a matrix.

$[\begin{array}{c} 1 & 0 & - 100 & 200 \\ 0 & 1 & - 120 & 0 \end{array}]$

Paso 3

Use the result matrix to declare the final solution to the system of equations.

$C - 100 x = 200$

$R - 120 x = 0$

Paso 4

The solution is the set of ordered pairs that make the system true.

$(200 + 100 x, 120 x, x)$
