Eliza made a mistake in this algebra problem. Identify which line has the error and explain what was done wrong and then solve.

2(x+10)-2=4x-5
2x+10-2=4x-5
2x+8=4x-5
8=2x-5

Answer:

x=11.5

Step-by-step explanation:

The second line has an error.

She didn't distribute the 2 and 10.

Here's the correct way:

Step 1: Simplify both sides of the equation.

2(x+10)-2=4x-5

2x+20-2=4x-5

2x+18=4x-5

Step 2: Subtract 4x from both sides.

2x+18−4x=4x−5−4x

−2x+18=−5

Step 3: Subtract 18 from both sides.

−2x+18−18=−5−18

−2x=−23

Step 4: Divide both sides by -2.

-2x/-2=-23/-2

x=11.5
