The solutions of the equation are -12 and 16
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative, if IxI = a, where a > 0, then
∵ 2Ix - 2I - 8 = 20
- At first add 8 to both sides
∴ 2Ix - 2I = 28
- Then divide both sides by 2
∴ Ix - 2I = 14
Now By using the notes above equate x - 2 by 14 and -14
∵ x - 2 = 14
- Add 2 to both sides
∴ x = 16
∵ x - 2 = -14
- Add 2 to both sides
∴ x = -12
The solutions of the equation are -12 and 16

Answer:
a triangle always equals 180 degrees so
63+ 2x+8 + x+7 =180
solve for x
and then plug it back into original equation
let me know if this makes sense
glad to help you more if needed
Step-by-step explanation:
I have no idea what the answer to that is or how to solve it but i LOVE UR PROFILE PICTURE
It is simple. 7/8 * 8 which is 7
