| 7 x - 6 | = | 4
Solve for x
x=\frac{2}{7}\approx 0.285714286
x = \frac{10}{7} = 1\frac{3}{7} \approx 1.428571429

|7x-6|=4
The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of 4 is 4.
7x-6=4 7x-6=-4
Use the definition of absolute value.
7x=10 7x=2
Add 6 to both sides of the equation.
x=\frac{10}{7} x=\frac{2}{7}
Divide both sides by 7.
