Answer 1

Do u know how to solve the first one
just isolate the x from the equation no#1 and then put the value of that isolated term into the other equation at the place of x

Answer 2

@Haseeb96 i dont get it

Answer 3

@Haseeb96 hello o.o

Answer 4

x-4y=5.......equation #1
x=3y-2,,,,,,,equation# 2
put x =3y-2 at the place of x in the equation #1
it would be
3y-2 -4y =5
-y=5+2
y=-7
now put y=-7 into the equation # 2
x = 3(-7) -2
= -21 -2
x = -23
so (x,y) = (-23,-7)
this is the correct answer
