Question

3x + 7 = 4, _________ is the value of x.​

Answer 1

3x + 7= 4

3x= 4-7

3x= -3

x= -3/3

x= -1

Answer 2

Answer:

=> The value of x is -1.

Step-by-step explanation:

Given that:-

$3x + 7 = 4$

To find:- The value of the expression,

To solve this expression, we have to use the transposition method:

As we have,

=> $3x + 7 = 4$

Now subtract both sides by $7$, we get

=> $3x + 7-7 = 4-7$

Simplifying it further, we get

=> $3x = 4 - 7$

Subtract the numbers, we get

=> $3x = -3$

Divide both sides by $3$,

=> $x = -1$

Hence, the required solution is -1.
