It is known that the solution of the equation x divided by 3-A + 1 = 0 is 3 larger than that of the equation 3x + A-2 divided by 3 = 0. Try to find the value of a and the solution of the equation

It is known that the solution of the equation x divided by 3-A + 1 = 0 is 3 larger than that of the equation 3x + A-2 divided by 3 = 0. Try to find the value of a and the solution of the equation

The solution of the equation x / 3-A + 1 = 0 is x = 3 (A-1) 1
The solution of the equation 3x + (A-2) / 3 = 0 is x = (2-A) / 9
Because ① is 3 larger than ②, ① - ② = 3, that is, x = 3 (A-1) - (2-A) / 9 = 3, a = 2
Substituting x = 3 in 1 means that the solution of the first equation is 3
Substituting x = 0 in 2 means that the solution of the second equation is 0

How to solve the equation 4x0.75-4a = 1.4

Four times 0.75 equals three
3-4a=1.4
3-1.4=4a
a=0.4
