Equation with abs

Solve this equation with absolute value member:

|3(3x-1)|=8 $    $

Result

x =  1.222
y =  -0.556

Solution:


3*(3x-1)=8

9x = 11

x = 11/9 ≈ 1.222222

Calculated by our simple equation calculator.


-3*(3y-1)=8

9y = -5

y = -5/9 ≈ -0.555556

Calculated by our simple equation calculator.
