Simplifying Expressions

Find like terms (terms that have the same variable).

x and 2x both have the variable x. 

5 and 2 are both constants.

Rewrite the expression with like terms together: x + 2x + 5 + 2

Combine like terms: x + 2x = 3x

Combine like terms: 5 + 2 = 7

So, this expression is simplified to: 3x + 7

3x & -x are like terms.

2 & 7 are like terms. 

Rewrite with these terms together:

3x - x + 2 + 7

Combine 7d & -2d: 7 - 2 = 5d

Combine 8 & -5: 8 - 5 = 3

So, expression is: 5d + 3

1. Find LIKE TERMS: 7d & -2d are LIKE. 8 & 6 are LIKE.

2. Rewrite with LIKE TERMS together: 7d - 2d + 8 + 6

3. Combine the coefficients of the LIKE TERMS: 7d - 2d = 5d, and 8 + 6 = 14.

Simplified Expression = 5d + 14
