Entiendo que multiplicar cada lado de una ecuación por un factor crea una ecuación equivalente que tiene la misma gráfica y las mismas soluciones que la ecuación original.

Puedo solucionar sistemas de ecuaciones multiplicando cada lado de una o de ambas ecuaciones por un factor, y luego sumando o restando las ecuaciones para eliminar una de las variables.

HSA-REI.A.1

Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
