$x = 13 or x = - 5$ $x=13orx=-5$

$2 | x - 4 | + 7 = 25$ $2|x-4|+7=25$

$2 | x - 4 | = 25 - 7$ $2|x-4|=25-7$

$| x - 4 | = \frac{18}{2}$ $|x-4|=18/2$

$| x - 4 | = 9$ $|x-4|=9$

now we break the modulus by adding plus and minus sign on the another side

$x - 4 = 9 or x - 4 = - 9$ $x-4=9orx-4=-9$

$x = 13 or x = - 5$ $x=13orx=-5$

How do you solve 2|x−4|+7=252|x - 4| + 7 = 25?
