The solution is the intersection point of the two lines
Explanation:
Multiply the second equation by
#2x - 3y = 13# #-2x -4y = 8# - Add equation 1 + equation 2:
#-7y = 21# - Divide by
#-7# to solve for#y# :#y = 21/-7 = -3# - Substitute
#y# into equation 1 and solve for#x# :
#2x -3(-3)=13#
#2x +9 = 13#
#2x = 4#
#x = 2#
The solution is the intersection point of the two lines
