Which equation is equivalent to 1/4x+1/5=2

x=9/8

Step-by-step explanation:

1/4x + 1/5 = 2/1 in this equation you can only find the L.C.M by using reciprocating method such that the numerators is exchange with the denominations as follows;

4x/1 + 5/1 = 1/2

You can equate the equation to 0

4x/1 + 5/1 - 1/2 =0. Now, LCM is 2

Multiply through by 2

2 X 4x/1 + 2 X 5/1 - 2 X 1/2 =0 we have; 8x + 10 - 1 = 0

8x = -9...then

X= -9/8//

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
