it will be 3.
Step-by-step explanation:
I think that is for your need
Y - x - 3 = 0
y = x + 3
y = x^2 - x - 12
x + 3 = x^2 - x - 12
x^2 - x - 12 - x - 3 = 0
x^2 - 2x - 15 = 0
(x - 5)(x + 3) = 0
x - 5 = 0 y = x + 3
x = 5 y = 5 + 3
y = 8
x + 3 = 0 y = x + 3
x = -3 y = -3 + 3
y = 0
so ur solutions are : (5,8) and (-3,0)
3x + 40 + x = 180
-40. -40
——————————-
4x. 140
—. ——-
4. 4
x = 35
X=9
A) 3x-7=34
3x= 34+7
3x= 41
x= 41/3
B) x-9=1
x=1+9
x=10
C) dude what is this
D) 4x+5=41
4x=41-5
4x=36
x=36/4
x=9 YAYY
Hope it helps!
