Question

In what step is there first an error. Please explain the error and how to correctly work the problem.

Answer 1

Answer:

Step 1 is wrong.

Step-by-step explanation:

Given: $2(10-13x)+9x=-34x+60$

Solving this we get;

$20-26x+9x=-34x+60$

=> $20-17x=-34x+60$

=> $-17x=-34x+60-20$

=> $-17x=-34x+40$

Step 1: $17x=-34x+40$

So, this is wrong.

Step 2: $17x=-34x+40$

Step 3: $51x = 40$

Step 4: $x=40/51$

Hence, Step 1 is wrong.

Answer 2

2(10-13x) +9x = -34x +60

Distributive property:

20 -26x +9x = -34x +60

Simplify:

20 -17x = -34x +60

Subtract 20 from both sides:

-17x = -34x -40

The error is in step 1, the 17x should be -17x
