Answer:3
Step-by-step explanation:
-9x+4=-8-5x
-4x+4=-8
-4x=-12
x=3
Answer:
Step-by-step explanation:
Add 5x so -9x+5x becomes -4x+4=-8 then subtract -4 and then -4+-8 becomes -12 and then solve for x which is -12/-4 which is 3.

Answer:
Option A, C and D are correction Option.
Step-by-step explanation:
Given Equation, -5x + 12 = Px + Q
We have to value of P and Q from given options such that equation has exactly one solution.
First simplify the equation,
-5x + 12 = Px + Q
-5x - Px = Q - 12
(-5 - P)x = Q - 12
from above P can not have value equal to -5 as if P = -5
we have (-5 - (-5))x = Q - 12
(-5 + 5)x = Q - 12
this equation has infinitely many solution as it removes x from the equation.
So, Option B is not our solution other than that All Options are our solution.
A).
P = 5 & Q = 12
⇒ (-5 - 5)x = 12 - 12
x = 0
C).
P = 5 & Q = -5
⇒ (-5 - 5)x = -5 - 12
-10x = -17
D).
P = -12 & Q = -12
⇒ (-5 - (-12))x = -12 - 12
7x = -24
Therefore, Option A, C and D are correction Option.
We are given equation : -5x+12=Px+Q.
Let us compare left and right sides of the equation.
On comparing Px = -5x.
Dividing both sides by x, we get
Px/x = -5x/x.
P = -5.
Let us compare other part of the given equation.
Q =12.
Therefore, we got P=-5 and Q =12.
Non of the given options seems correct.
Please check the option have P=-5 and Q =12.
