What is the justification for each step in the solution of the equation 3(2x + 7) - 4 = 53 - 3x? step 1: 3(2x + 7) - 4 = 53 - 3x step 2: 6x + 21 - 4 = 53 - 3x step 3: 6x + 17 = 53 - 3x step 4: 9x + 17 = 53 step 5: 9x = 36 step 6: x = 4 (doing this again since i forgot to add the steps, ! )

Step 1: 3(2x + 7) - 4 = 53 - 3x (the equation)
Step 2: 6x + 21 - 4 = 53 - 3x. (order of operations multiplication ( ) first)

Step 3: 6x + 17 = 53 - 3x (subtraction next, getting variables on left side)

Step 4: 9x + 17 = 53 (to make equation one sided, add 3x to both sides making the left side = 9x) (and subtract 17 from 53 on right side) OR do next step

STEP 5: 9x = 53-17 (I WOULD ADD THIS STEP, subtracting 17 from both sides)

Step 6: 9x = 36

STEP 7: x=36/9

Step 8: x = 4
