It is known that the solution of the equation 2x + 3A = 1 + A is the same as that of x = 4-2


 



One question: it is known that the solution of equation 4 (x 2) - 2 = 53a about X is not less than the solution of equation (3a 1) x / 3 = a (2x 3) / 2, and the value range of a is obtained
Second question: compare 3a with 2A plus 1


It is known that the solution of the equation 4 (x + 2) - 2 = 5 + 3A about X is not less than the solution of the equation (3a + 1) x / 3 = a (2x + 3) / 2. Find the value range of A



It is known that the solution of the equation 4 (x + 5) - 2 = 5 + 3A about X is not less than the equation (2a + 1) x / 3 = a (3x + 3) / 2, and the value range of a is obtained


By solving the first system of equations, we can get x = (3a-13) / 4
2,x=3a/(2-5a)
So, (3a-13) / 4 > 3A / (2-5A)
15a^2+83a+26>0



We know that the solution of the equation 3A + x = a2x + 3 about X is: x = 4, find: a-2a + 3a-4a + 5a-6a + +99a-100a


Substituting x = 4, we can get: 3A + 4 = A8 + 3, the solution is: a = - 823, the original formula = (a-2a) + (3a-4a) + (5a-6a) + +(99a-100a) = - 50a, when a = - 823, the original formula is 40023
