Question

a) Find x.



25 − 3x = 40

Answer 1

Answer:

25 - 3x = 40

-3x = 40 - 25

-3x = 15

x = 15/-3

x= -5

Answer 2

Answer:

=> The value of x is -5.

Step-by-step explanation:

Given that:-

$25 -3x = 40$

To find:- The value of the expression,

We must use the transposition method to calculate the value of x:

As we have,

=> $25 -3x = 40$

First of all, rearrange the terms:

=> $-3x +25=40$

Now subtract both sides by $25$,

=> $-3x +25-25=40-25$

Simplifying it further, we get

=> $-3x =40-25$

Subtract the numbers,

=> $-3x = 15$

Divide both sides by $-3$,

=> $x = -5$

Hence, the required solution is -5.
