Subtract 1l from both side to get

-5lx = 10 - 1l

Divide by - 5l to get

X = 10 +.2l

Mohamed · Answer 2

This equation is unsolvable ... to isolate for x you divide by - 5 on both sides, then you get

|x + 1|=-2

but it's impossible for absolute value to be negative, so it's unsolvable.

(absolute value cannot be negative because it represents a number's distance from zero)
