It is known that the solution of the equation 3x + a = 0 about X is 5 times larger than that of the equation 3x-a = 0=

It is known that the solution of the equation 3x + a = 0 about X is 5 times larger than that of the equation 3x-a = 0=

The solution x = - A / 3 of 3x + a = 0
If the solution is 5 larger than that of the equation 3x-a = 0, then x = - A / 3 + 5
Then 3 (- A / 3 + 5) - a = 0
The solution is a = 15 / 2

How many solutions does equation 1 / 3x-y / 4 = 5 have? Are x = 1 / 3 and y = 1 / 4 the solutions of this equation? Why

Innumerable group solutions
X = 1 / 3, y = 1 / 4 into the equation 1 / 3x-y / 4 = 7 / 144 is not equal to 5, so it is not the solution of the equation
