Answer 1

Answer:

x=21/40

Step-by-step explanation:

First get common denominators

3/8 *5 to top and bottom is now 15/40

3/20 *2 to top and bottom is now 6/40

isolate the X

x-15/40=6/40

+15/40    +15/40

x=21/40

Answer 2

Answer:

x = $\frac{21}{40}$

Step-by-step explanation:

Given

x - $\frac{3}{8}$ = $\frac{3}{20}$

Multiply through by 40 ( the LCM of 8 and 20 ) to clear the fractions

40x - 15 = 6 ( add 15 to both sides )

40x = 21 ( divide both sides by 40 )

x = $\frac{21}{40}$
