The equation is solved as follows:

(x+25)+(x-27)+x= 103

x+25+x-27+x= 103

3×x+25-27= 103

3×x= 103

x = 35

Extended data:

1. Steps to solve the equation:

1, denominator first.

If there are brackets, remove them.

3. Need to move items, move items.

4. Merge similar projects

5. When the coefficient reaches 1, an unknown value is obtained.

Step 6 write "thank you" at the beginning

For example:

3+x= 18

Solution: x= 18-3

x= 15

Second, the common solutions:

1, bracket deletion: Use bracket deletion rule to delete brackets from the equation.

For example: 4x+2 (79-x) =192; (x+25)+(x-27)+x = x+25+x-27+x；

2. Move the term: move the unknown term to the left and the constant term to the right.

Example: 3+x= 18, solution: x =18-3;

3. Merge similar terms: transform the equation into a monomial.

4. Formula method: There are some equations, and the general form of solutions has been studied and become fixed formulas, which can be used directly. Generally solvable multivariate higher-order equations have formulas to follow.
