Short way to solve system of equations by elimination

To solve system of equation by elimination, check if the values of x or y are lined up and have the same value.

Or if the are not, take the numbers in x or y to multiply. Use the first to multiply the second equation and the second to multiply the first equation

Example is, for the first step which is in italic form is

         2x + 3y =64...equation 1

          2x - 6y = 75...equation 2

you can just eliminate for x by taking away equation 2 from equation 1

Or for step two which is in light form is

        4x + 3y =64...equn 1

        3x + 7y =80...equn2

to eliminate x, multiply equation 1 by 3 and equation 2 by 4

it will be   12x +12y =192

                 12x +28y =320

now you can solve.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
