Answer:
x=3
Step-by-step explanation:
Because the line lies on x =3
Answer:
x = -7/2 multiplicity 2.
Step-by-step explanation:
4x^2 + 28x + 49 = 0
(2x + 7)(2x + 7) = 0
This is a perfect square.
2x + 7 = 0, so:
x = -7/2 multiplicity 2.
X=56+4y
6x-6y=678
x-y=113
x=113+y
113+y= 56+4y
57=3y
y=19
x=132
Answer:
-8
Step-by-step explanation:
first combine like terms 5x+5x=10x
then subtract 5 from -75= -80
divide -80 by 10= -8
you are left with -8=x
