X/20 - 2/5 = 3/4

Plz help :)

x = 23

Step-by-step explanation:

simplify both sides of the equation then isolate the variable.

x = 23

Step-by-step explanation:

x/20 + 20 ( -2/5 )/20 = 3/4

combine fractions with common denominator

x - 8/20 = 3/4

Multiply all terms by the same value to eliminate fraction denominators

20 . x - 8/20 = 3/4 = 20. 3/4

Cancel multiplied terms that are in the denominator

x - 8 = 20 . 3/4

Multiply the numbers

x - 8 = 15

Add 8 to both sides of the equation

x - 8 + 8 = 15 + 8

simplify

add the numbers

x = 23
