PLease help me understand this with the substitution method.
can you please find x and y. I got x=4.25 and y=3 can you please tell me what I did wrong.
OK,, SUBSTITUTION method
The FIRST equation tells you what y = Substitue this value of y in to the 2nd equation....
-3x - 3 (-5x-17) =3 and solve for 'x'......
then use this value of 'x' that you find and substitute back into EITHER of the equations to find the 'y' value
-3x + 15x +51 = 3
12x + 51 = 3
12x = -48
x = - 4 y = -5(-4)-17
y = 3
