solve the system: x-2y = 5 2x-y = 3 solve the system: x-2y = 5 2x-y = 3

You may
also consider the alternative method, that uses determinants, such that:

x-2y
= 5

2x-y = 3

Form the determinant of the system such
that:

= class="AM">

class="AM">

You need to find the variable x such
that:

class="AM">

class="AM">

You need to find the variable y such
that:

class="AM">

class="AM">

Hence, evaluating the
solutions to the system yields and class="AM"> .
