3/4 x-2 =2/5
Multiply both sides of the equation by 20
20(3/4 x-2)=20x 2/5
Distribute 20 through the parentheses
20x 3/4 x-20 x2=20 x2/5
Reduce the numbers with the greatest common factor 5
20 x 3/4 x -20 x2=4x2
Reduce the numbers with the greatest common factor 4
5x 3x-20x2=4x2
Multiply the numbers
5x3x-40=4x2
multiply the numbers
5x3x-40=8
Calculate the product
15x-40=8
Answer: 16/5
