Question

5x-12=2x-8 answer for this

Answer 1

Answer:

$5x-12=2x-8\quad :\quad x=\dfrac{4}{3}\quad \left(\mathrm{Decimal}:\quad x=1.33333\dots \right)$

Step-by-step explanation:

$5x-12=2x-8$

$\mathrm{Add\:}12\mathrm{\:to\:both\:sides}$

$5x-12+12=2x-8+12$

Simplify;

$5x=2x+4$

$\mathrm{Subtract\:}2x\mathrm{\:from\:both\:sides}$

$5x-2x=2x+4-2x$

Simplify;

$3x=4$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\dfrac{\cancel{3}x}{\cancel{3}}=\dfrac{4}{3}$

Simplify;

$x=\dfrac{4}{3}$

Answer 2

Question:-

Find the value of x in the given equation:-

5x-12=2x-8.

Answer:

The value of x is 4/3.

Step-by-step explanation:

For solving any equation, we have to first

keep all the variables in one side and the

constants in another side.

The sides may be any .

Here In taking the variables in the LHS.

Taking the variables in LHS and

constants in RHS is more convenient

then vice - versa.

When we interchange the sides of any

number, we should keep in mind that we

have to change the signs too.

We have to change - to + , + to - , X to ÷ and ÷ to X.

So here the equation becomes :-

5x-2x= -8+12

Now solving the equation, we get:-

=>3x=4

Now again we have to interchange the

signs.

=>x= 4/3

Hence the value to x is 4/3.
