Answer :
Answer:
The solution is the point (2,-5)
Step-by-step explanation:
we have
[tex]3x+2y=-4[/tex] ------> equation A
[tex]4x-y=13[/tex] ------> equation B
Multiply equation B by 2 both sides
[tex]2(4x-y)=2*13[/tex]
[tex]8x-2y=26[/tex] ------> equation C
Adds equation A and equation C
[tex]3x+2y=-4\\8x-2y=26\\---------\\3x+8x=-4+26\\11x=22\\x=2[/tex]
Find the value of y
substitute the value of x in equation A
[tex]3(2)+2y=-4[/tex]
[tex]2y=-4-6[/tex]
[tex]2y=-10[/tex]
[tex]y=-5[/tex]
The solution is the point (2,-5)
