Due in 2 a system of equations and it’s solution are given below. system a. x-y=3 -2x+4y=-2 solution: (5,2) complete the sentences to explain what steps were followed to option the system of equations below. system b x-y=3 2x=10 to get to system b the (first/second) equation in system a was replaced by the sum of that equation and the (first/second) equation multiplied by () . the solution to system b (is/ is not) the same as the solution to system a.

  To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4 . The solution to system B is the same as the solution to system A.

The first equation of system B is the same as the first equation of system A, so nothing was done to it. The second equation has x as a surviving variable, so the variable y was eliminated from the second equation. That can be done by adding something to the second equation that includes -4y on the left side of the equal sign.

That "something" can be the product of 4 and the first equation, since the first equation has -y on the left side of the equal sign.

Indeed, adding 4 times the first equation to the second equation of system A will result in the equations of system B. Since we have not violated any properties of equality in peforming that addition, the solution to system B is the same as the solution to system A.
