Answer:
Hello mate
Step-by-step explanation:
(3x+1)/(x+1)}+{(x+1)/(3x+1)} = 5/2
[(3x + 1)^2 + (x + 1)^2]/(3x+1)(x+1) = 5/2
(10x^2 + 8x + 2)/(3x^2 + 4x + 1) = 5/2
20x^2 + 16x +4 = 15x^2 +20x + 5
5x^2 - 4x -1 = 0
5x^2 -(5 - 1)x = 0
5x^2 - 5x + x - 1 = 0
5x(x - 1) + 1(x - 1) = 0
5x + 1 = 0
x = -1/5
or
x -1 = 0
x = 1
so answer will be 1,-1/5(option 3)
Answer:
3x+1
x=1/3
Step-by-step explanation:
So, first we are having an equation 3x+1. So to solve this answer we will move X to the left side and 3 to the right of the equal Sign, which Is equal to X=1/3. Here 3 is getting divided cause on the left side it is being multiplied by X so when we will move it to the right i mean to the right of the equals sign it will get Divided so it will be 1/3
and the equation will be X=1/3
