Solve the equation:<br> 5|2x-7|=20

MA_775_DIABLO [31]

Answer:

x = $\frac{11}{2}$ , $\frac{3}{2}$

Step-by-step explanation:

First, isolate the absolute value:

5|2x - 7| = 20

divide both sides by 5:

|2x - 7| = 4

break into 2 equations:

2x - 7 = 4, 2x - 7 = -4

solve both equations and collect solutions:

2x = 11, 2x = 3

x = $\frac{11}{2}$ , $\frac{3}{2}$
