Equation with abs

Solve this equation with absolute value member:

∣3(3x−1)∣=8|3(3x-1)|=8


Correct result:

x =  1.222
y =  -0.556

Solution:


3•(3x-1)=8

3•(3•x-1)=8

9x = 11

x = 119 ≈ 1.222222

Calculated by our simple equation calculator.

-3•(3y-1)=8

-3•(3•y-1)=8

9y = -5

y = -59 ≈ -0.555556

Calculated by our simple equation calculator.
