Question

If f(x)= |4x - 1|, find the value of x if(x) = 7

Answer 1

f(x) = | 4x - 1 | .....when f(x) = 7
7 = | 4x - 1 |

4x - 1 = 7               -(4x - 1) = 7
4x = 7 + 1               -4x + 1 = 7
4x = 8                      -4x = 7 - 1
x = 8/4                     -4x = 6
x = 2                          x = -6/4
                                  x = - 3/2

solutions are x = -3/2, 2

Answer 2

x=2 i hope that helps soo yeah
