Who can put all the solutions and formulas of linear equation of one variable, in a word, is what we need to use in the first day of junior high school

The teaching objectives are: 1. To make students understand and master the equation with letter coefficient and its solution; 2. To understand the meaning of formula deformation and master the method of formula deformation; 3. To improve students' operation and reasoning ability

It is known that the square of AX + 3x + 11 = 2 (the square of x-x) + 3a is a linear equation of one variable with respect to x, then its solution is______

Ax & # 178; + 3x + 11 = 2 (X & # 178; - x) + 3aax & # 178; + 3x + 11 = 2x & # 178; - 2x + 3A (A-2) x & # 178; + 5x + 11-3a = 0 because it is a univariate linear equation, so A-2 = 0A = 2. Given that the square of AX + 3x + 11 = 2 (the square of x-x) + 3a is a univariate linear equation about X, its solution is__ a=2____ ...

If 7 + 3A / 2 x2-3x + 1 = 0 is a linear equation of one variable with respect to x, find the value of A

Is it: (7 + 3a) / 2 x & # 178; - 3x + 1 = 0
Because it's a linear equation of one variable
So the coefficient of the term x & # is 0
(7+3a)/2=0
a=-7/3

If a-3x ^ | a | - 2 + 5 = 0 is a linear equation of one variable about X, find the value of a ^ 3-3a ^ 2 + a?

Is the equation (A-3) * x ^ (| a | - 2) + 5 = 0
Because the equation is a linear equation of one variable with respect to X,
So A-3 ≠ 0, and | a | - 2 = 1,
The solution is a = - 3,
So a ^ 3-3a ^ 2 + a = - 27-27-3 = - 57
