What is the value of x in the equation 1/2x - 3/4 = 3/8 - 5/8
Kitty [74]

The answer

x = 1

step by step

\frac{1}{2} x -  \frac{3}{4}  = \frac{3}{8}  -  \frac{5}{8} \\  \frac{1}{2} x = \frac{3}{8}  -  \frac{5}{8} +  \frac{3}{4}  \\  \frac{1}{2} x = \frac{3}{8}  -  \frac{5}{8} +  \frac{6}{8}  \\  \frac{1}{2}x =   \frac{4}{8}  \\  \frac{1}{2} x =  \frac{1}{2}  \\ x = 1
