Question

Solve the equation below
-6x-21=51+3x

Answer 1

Answer:

therefore x= -8

Step-by-step explanation:

-6x-21=51+3x

= -6x-21-3x=51 (transpose 3x from R.H.S to L.H.S)

= -6×-3x=51+21 (transpose 21 from L.H.S to R.H.S)

= -9x=72

= x=72/ -9

=therefore x= -8.

Answer 2

Answer:

The value of the equation is -8.

Step-by-step explanation:

As per the data given in the equation,

We have to find the value of the equation,

The given equation,

$-6x-21=51+3x$

Rearrange the terms, we get

=> $-6x-21=3x+51$

Add $21$ on both sides, we get

=> $-6x-21+21=3x+51+21$

Simplifying it further, we get

=> $-6x=3x+72$

Now subtract both sides by $3x$, we get

=> $-6x-3x=3x+72-3x$

=> $-9x = 72$

Divide both sides by $-9$,

=> $x = -8$

Hence, the required solution is -8.
