Question 85366
I'm assuming that the problems are divided into columns

*[invoke solving_linear_system_by_elimination 5, -2, -5, 8, -4, 16]


*[invoke solving_linear_system_by_elimination 4, -12, 5, 10, 2, 7]


{{{y – 5x = 3}}}
{{{y = 2x – 4 }}}


{{{y – 5x = 3}}}
{{{y - 2x = 4 }}} Subtract 2x from both sides
*[invoke solving_linear_system_by_elimination -5, 1, 3, -2, 1, -4]


{{{-x + 3y = -1}}}
{{{y = -5x + 3 }}}



{{{-x + 3y = -1}}}
{{{y+5x = 3 }}} Add 5x to both sides
*[invoke solving_linear_system_by_elimination -1, 3, -1, 5, 1, 3]
