Simplify (3x + 5) + (2x - 9) - (4x + 3).
Solution:
The given expression can be solved as follows:
(3x + 5) + (2x - 9) - (4x + 3)
By grouping the variables and the constants we have,
3x + 2x - 4x + 5 - 9 + 3
= 5x - 4x + 8 - 9
= x - 1
Let us take another example of simplification:
Simplify: (a4 + a3 - a) - (a3 - 3a2 + 5a) + (a3 - 4a + 2) - (2a - 3)
Grouping the terms we have,
a4 - a3 + a3 +3a2 - a -5a - 4a - 2a + 2 + 3
a4 + 3a2 - 12a + 5
Simplify (3x + 5) + (2x - 9) - (4x + 3).
Summary:
Simplifying (3x + 5) + (2x - 9) - (4x + 3), we get x - 1
