Simplify the expression 8 - 2x + 12x - 3. Show that your answer is true for x=2

Simplified Expression if x=2:

8-2x+12x-3 Original Problem

8-2 (2) + 12 (2) - 3 Substitute 2 in for variable "x"

8-4+24-3 Subtract 4 from 8

4+24-3 Subtract 3 from 24

4+21 Add 4 to 21

25 The answer is 25 if x=2

Simplified Expression w/o x=2:

8-2x+12x-3 Original Problem

-2x+12x+5 Subtract 3 from 8

10x+5 Add - 2x to 12x

10x+5 Simplified without x=2

To check if x=2:

10x+5 Original Problem

10 (2) + 5 Substitute 2 in for the variable "x"

20+5 Multiply 10 by 2

25 Add 5

25 Final Answer

The step (s) to get to the answer I got is on the right sides of the equation (s).

8 - 2x + 12x - 3

8 + (-2x + 12x) - 3

8 + 10x - 3

8-3 + 10x

5 + 10x

10x + 5
