{{{y -20=-6x}}}….write this one in the standard form too

{{{6x + y =20}}}….

Here is solution (using addition):

*[invoke solving_linear_system_by_elimination 4, -3, 10, 6, 1, 20]


b. 

{{{ y= 3x + 6 }}}…. write this one in the standard form

{{{-3x + y= 6 }}}….

{{{ 6x + 2y = 12}}}…. this is the standard form

Here is solution (using substitution):


*[invoke solving_linear_system_by_substitution -3, 1, 6, 6, 2, 12]
