Question

3 (4x - 3) - 2 (5x - 8) = 17​

Answer 1

$\huge\fbox\green{AnsweR}$

3(4x - 3) - 2(5x - 8) = 17

12x - 9 - 10x + 16 = 17

12x - 10x -9 + 16 = 17

2x + 7 = 17

2x = 17 - 7

2x = 10

x = 10 ÷ 2

x = 5

Answer 2

Answer:

Value of x = 5

Step-by-step explanation:

Given :

3(4x-3)-2(5x-8)=17

To find :

The value of x

Solution :

$\leadsto\sf{3(4x-3)-2(5x-8)=17}$

Used cross multiplication

$\leadsto\sf{12x-9-10x+16=17}$

Changed the sign - to + because -2×-8 = 16.

Here, (-)×(-)=+

$\leadsto\sf{12x-10x-9+16=17}$

$\leadsto\sf{2x+7=17}$

$\leadsto\sf{2x=17-7}$

$\leadsto\sf{2x=10}$

$\leadsto\sf{x=\dfrac{\cancel{10}}{\cancel{2}}}$

$\leadsto\sf{x=5}$

So , the value of x is 5 .
