Al resolver un sistema de ecuaciones usando el método de elinación, ¿cuál corresponde al paso 1? Resolver la ecuación resultante

Multiplicar si es necesario, para poder cancelar la misma variable

Sustituir y resolver para determinar el valor de la segunda variable

Sumar ambas ecuaciones: Ec 1 y Ec 2

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
