Solution:

2^986

Solution:

step 3 is wrong

Solution:

Draw a tilted line on 1st plus (+) operator, + will become 4 :-)
The equation then becomes true: 545+5=550.

Solution:

.05

Given the equation 8/x = 160, when you solve for x, you indeed get:

8/x = 160

To find x, you can simply invert the fraction:
x/8 = 1/160

Now, to isolate x, multiply both sides by 8:
x = 8 * (1/160)
x = 8/160
x = 1/20 = 0.05
