What is the answer to this math problem (4X/5)+(3X+5/4)=4?

As written, question reads:-
4x / 5 + 3x + 5/4 = 4
16x + 60x + 25 = 80
76 x = 55
x = 55 / 76

However, if question is :-
4x / 5 + (3x + 5) / 4 = 4
16x + 15x + 25 = 80
31 x = 55
x = 55 / 31

In each case, the numbers don`t look friendly !!!

4x/5 + (3x + 5)/4 = 4
16x/20 + (15x + 25)/20 = 4
16x + 15x + 25 = 80
31x = 55
x = 55/31 or 1 24/31

Answer: x = 55/31 or 1 24/31

Proof:
(4[55/31])/5 + (3[55/31] + 5)/4 = 4
(220/31)/5 + (165/31 + 5)/4 = 4
(220/31)/5 + (165/31 + 155/31)/4 = 4
(220/31)/5 + (320/31)/4 = 4
(880/31 + 1,600/31)/20 = 4
(2,480/31)/20 = 4
80/20 = 4
4 = 4

in case you do not comprehend what's on the different factor of the equals sign, you could simplify the equation to 6x-4y=?, yet you nevertheless do not comprehend the respond, because of fact which you do not comprehend what's on the different factor of the equals sign. in case you start up with the equation (3x-2y)2=0, then we are in a position to remedy it like so: a million. Divide the two facets by using 2 --> 3x-2y=0 2. upload 2y to the two facets --> 3x=2y With this you could only remedy x in terms of y or y in terms of x. To get actual values for x and y you want a 2nd equation containing x and/or y. working example, in case you have the equation (3x-2y)2=0 and the equation 6x=4 then you definately can remedy like so: a million. Divide the two facets by using 2 --> 3x=2 Now you comprehend that 3x= 2, and you will plug that into the 1st equation: a million. (2-2y)2=0 2. Divide the two facets by using 2 --> 2-2y=0 3. upload 2y to the two facets --> 2=2y 4. Divide the two facets by using 2 --> a million=y (or y=a million) so which you comprehend that y=a million, and that 3x=2. to properly known what x equals: The equation is 3x=2 a million. Divide the two facets by using 3 --> x=2/3 x=2/3 and y=a million.

(4x/5)+(3x+5/4)=4
4x/5+3x+5/4=4
4x/5+3x=4-5/4
19x/5=11/4
76x=55
x=55/76

4/5 x + 3x =4 - 5/4
3 4/5x =2 3/4
x= 2 3/4 / 3 4/5
=55/76

(4x/5) + (3x + 5/4) = 4
16x/20 + (15x + 25)/20 = 4
16x + 15x + 25 = 80
31x = 80 - 25
31x = 55
x = 55/31
x = 1 24/31
