Question

Solve the equation: I2x-10I=26 ?

Answer 1

the 2 vertical are the modulus function which mean the value is always positive

so the 2x - 10 may be positive or negative
so you need to convert to 2 equations and solve them

Answer 2

* 2 vertical lines

Answer 3

idk how to do this

Answer 4
