Question

Q4. If - 2(x - 3) = - x, then the value
of x must be​

Answer 1

Answer:

X=3

Step-by-step explanation:

-2x+3=-x

3= -x+2x

3=X

hope it helps :))

Answer 2

Answer:

First, we can just compare both sides and conclude that x equals 3.

x=3

Method 2:

This is a bit long method but it incorporates all the required steps. To solve it we need to take natural log “ln” both sides and we would get

ln2^x = ln2^3

by using the property of ln, we can write

xln2 = 3ln2

x=3

Now if x=3, putting the value of x and 3^x would be

3^3 = 27

Below I am going to attach a picture of its solution as well. Hopefully, everyone would get the concept of solving such questions.
