1. write each problem on paper. 2. write the expression. 3. combine 'like terms' to write the standard form of the expression. then . . 4. match each expression to the standard form of the expression. question 1 options: 4x + 11 6x -14x - 18 -3x + 2 -4x - 4 -8x + 9 match. 1. find the sum of -3x + 9x 2. find the sum of -7x and 4x + 2 3. find the difference when 6x is subtracted from 2x - 4 4. find the difference when -3x - 7 is subtracted from x + 4 5. find the result when 13x + 2 is subtracted from 11 + 5x 6. find the result when -18x - 4 is added to 4x - 14

1.  6x

2. -3x + 2

3. -4x - 4

4. 4x + 11

5. -8x + 9

6. -14x - 18

Step-by-step explanation:

1. Finding sum of -3x+9x

As both the terms have different signs, the terms will be subtracted and the sign in the answer will be of the larger terms (the term with greater coefficient)

So the answer of -3x+9x is 6x

2. Finding the sum of -7x and 4x + 2

For sum,

-7x + (4x+2)

= -7x + 4x + 2

= -3x + 2

3. Finding the difference when 6x is subtracted from 2x - 4

= 2x - 4 - (6x)

= 2x - 4 - 6x

= 2x - 6x - 4

= -4x - 4

4. Finding the difference when -3x - 7 is subtracted from x + 4

= (x+4) - (-3x-7)

= x + 4 + 3x + 7

= x + 3x + 4 + 7

= 4x + 11

5. Finding the result when 13x + 2 is subtracted from 11 + 5x

= (11 + 5x) - (13x + 2)

= 11 + 5x - 13x - 2

= 5x - 13x + 11 - 2

= -8x + 9

6. Finding the result when -18x - 4 is added to 4x - 14

= (4x - 14) + (-18x - 4)

= 4x - 14 - 18x -4

= 4x - 18x - 14 - 4

= -14x - 18

..

it’s supposed to be -4+45=41
