Answer:
The value of x is -9, 3/4 and 3.
Step-by-step explanation:
In order to find the value of x, tou have to let f(x) equals to 0 :
Let f(x) = 0,
(x-3)(x+9)(4x-3) = 0
x - 3 = 0
x = 3
x + 9 = 0
x = -9
4x - 3 = 0
4x = 3
x = 3/4
Answer:
use -4y for x in the second equation
-4 y + 5 y = 2
so
y = 2
then x = -4(2) = -8
(-8 , 2)
Step-by-step explanation:
Answer:
(a) 4
(b) 2/3
Step-by-step explanation:
(a) 4y+3=19
4y=19-3
4y=16
y=4
(b) 12n-3=5
12n=5+3
12n=8
n=8/12
n=2/3
