I WILL GIVE BRAINLIEST Solve: 2(2x + 9) = 5x + 72 Step 1: 4x + 18 = 5x + 72
Step 2: 9x + 18 = 72
Step 3: 9x = 54
Step 4: x = 6

Which is the first incorrect step in the solution shown above?

Step 1
Step 2
Step 3
Step 4

The first incorrect step would be the second, I think.

Step-by-step explanation:

You need to distribute:

2(2x+9) = 5x + 72

4x + 18 = 72

Then subtract 18 from both sides of the equation. Step 2 dosnt do this.

Next you simplify and get: 4x = 5x + 54

Subtract 5 from both sides of equation

Finally simplify and you get: -x = 54

Solve: 2(2x + 9) = 5x + 72

Step 1: 4x + 18 = 5x + 72

Step 2: 9x + 18 = 72

Step 3: 9x = 54

Step 4: x = 6

Step 1: 4x + 18 = 5x + 72

Step 2: x + 72 = 18

Step 3: x = 18-72

Step 4: x = -54

Which is the first incorrect step in the solution shown above?

→First incorrect step in the solution shown above is Step 2.
