How do you solve the following linear system: # -x+2y=-6 , 5x-2y=-35 #?
#-x + x + 2y = - 6 + x# # 2y + 6 = -6 + x +6 # #2y + 6 = x#
Substitute the expression in step 3 in for
... and use the value of
There aren't negative signs on both sides of the equation, so the value of
Since these are linear systems, these are the only solutions to the system. You can always rewrite both equations in terms of
