Question

13. If 5x + 8 = 3x-6, then x

Answer 1

Answer:

If 5x + 8 = 3x-6, then x is -7

Step-by-step explanation:

5x + 8 = 3x-6

5x - 3x = -6 - 8

2x = -14

x = -14/2

x = -7

Answer 2

Answer:

=> The value of x is -7.

Step-by-step explanation:

Given that:-

$5x + 8 = 3x-6$

To find:- The value of the expression:

Here we will use the transposition method.

We have to follow these steps:-

( i ) First of all, we have to identify the variables and the constants.

( ii ) Get the variable to one side of the equation. Maintain equation balance while calculating.

( iii ) Then solve the expression of both sides by using various mathematical operations. Simplify both sides.

As we have,

=> $5x + 8 = 3x-6$

Now subtract both sides by $8$,

=> $5x + 8 -8= 3x-6-8$

=> $5x=3x-14$

Subtract both sides by $3x$,

=> $5x-3x=3x-14-3x$

=> $2x = -14$

Divide both sides by $2$,

=> $x = -7$

Hence, the required solution is -7.
