Answer:
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.
