The answer is 3 because you have to add 3 on both sides. Then you will get 5x =15 then to get X by itself you would have to divide by 5 on Both sides 5x/5 cancels its self out then your left with x 15/5=3 so you will get X=3 therefor the number is 3

5x-3=12
+3 +3
5x=15
———-
5 5

X=3

Consider the equation below

s344n2d4d5 [400]

Answer: B

Step-by-step explanation:

Let's solve the given equation. Then we can see which other equation has the same answer.

-5n+31=-14n-5

36=-9n

n=-4

We need to fina another equation that gives n=4 as the answer.

A. Incorrect

3-6n+3n=-3+4-4n

3-3n=1-4n

n=-2

B. Correct

$\frac{11}{4} n+2=-3+\frac{3}{2}n$

$\frac{5}{4}n=-5$

$n=-4$

C. Incorrect

1=0.75n+3.25

-2.25=0.75n

n=-3

D. Incorrect

-1-22n=-20n-9

8=2n

n=4
