Question

root6x+7 - (2x-7)=0 ​

Answer 1

Answer:

-3.5

Step-by-step explanation:

We can solve it as follows:

$\sqrt{6x + 7 - (2x - 7)} = 0 \\ squaring \: both \: sides \\ {(\sqrt{6x + 7 - (2x - 7)})}^{2} = {0}^{2} \\ 6x + 7 - 2x + 7 = 0 \\ 4x + 14 = 0 \\ 4x = - 14 \\ x = \frac{ - 14}{4} \\ x = - 3.5$
