Question

15. 3(x + 2) - 2(x - 1) = 7

Answer 1

Answer:

3(x+2)-2(x-1)=7

3x+6-2x+2=7

x+8=7

x=7-8

x=-1

Answer 2

Answer:

The value of the equation will be -1.

Step-by-step explanation:

In the context question asked that,

We have to find the value of the given equation,  

Given that,

$3(x + 2) - 2(x - 1) = 7$

Here we will use the transposition method,

Now, distributing the terms we get

=> $3x + 6 - 2x - 2 = 7$

Add the numbers,

=> $3x + 8- 2x = 7$

Combine the like terms,

=> $x + 8 = 7$

Transposing 8 on the right side,

=> $x = 7 - 8$

=> $x = -1$

Hence, the required solution is -1.
