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//

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
