Step-by-step explanation:
5x-4y=-3
y=5x+3/4--(1)
y=-3x+5--(2)
compare the two equations
5x+3/4=-3x+5
5x+3=4(-3x+5)
5x+3=-12x+20
now add 12x on both sides
17x+3=20
now subtract 3 from both sides
17x=17
now divide 17 from both sides
x=1
plug this value of x on any one of the above 2 equation I am using (1)
y=5(1)+3/4
y=5+3/4
y=8/4
y=2
