Step-by-step explanation:
f(-1)=3×(-1)²-4×(-1)
=3×1-4×(-1)
=3+4
=7
hope it helps.
-2x+3(x-1) = -6
-2x + 3x - 3=-6
x-3 = -6
x = -6+3
x= -3
y=x-1
y=-3-1
y= -4
Hope this helps=)
No, because all the sides have to be equal
Answer:
multiply equn q by 3 .
when u will multiply equn 1 by 3 then you will get,9x+3y=39 and second equn is4x_3y=13 so, y can be cancelled and get the value of x for the first time and by putting the value of x you will find the value of y.
