Answer: x = -18

Step-by-step explanation: The first step can be changed but I decided to subtract 11 on both sides so that the x’s are found on one aside and the numbers are found on the other. Then in the second step, I combined like terms, the x’s. Then I divided both sides by -4 to cancel out the -4 next to the x and 72/(-4) is -18.

- x - x + 11 - 2x = 83 please show step by step!!​-example-1

Answer:


x=-18

Explanation:

Given


-x-x+11-2x=83

Step 1: Combine Like Terms on LHS


-x-x+11-2x=83\\-2x+11-2x=83\\-4x+11=83

Step 2: Subtract 11 on both sides


-4x+11=83\\-4x+11-11=83-11\\-4x=72

Step 3: Divide both sides by -4 to isolate the x-variable


-4x=72\\\\(-4x)/(-4)=(72)/(-4)\\ \\ x=-18

Final Answer


x=-18
