Question

Solve the equation (x - 4) - (x + 7) = 8x

Answer 1

For this case we have the following equation:

$(x-4) - (x + 7) = 8x$

We have to:

$- * + = -$

So, rewriting the expression we have:

$x-4-x-7 = 8x$

We add similar terms from the left side:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

$-11 = 8x$

We divide between 8 on both sides:

So:

$x = - \frac {11} {8}$

ANswer:

$x = - \frac {11} {8}$
