Answer:
4, 2, 1, 3
Step-by-step explanation:
2/3(x + 21 - 1) - 162
We used the formula for PEDMAS
Step 1
2/3(x + 20) - 162
Step 2
2/3(x + 20) = 162
Multiply both sides by 3/2
Step 3
3/2× 2/3(x + 20) = 162 × 3/2
x + 20 = 81 × 3
x + 20 = 243
Subtract 20 from both sides
x + 20 - 20 = 243 - 20
Step 4
x = 223
Therefore, according to the above calculation, the correct steps to solve this question is 4, 2, 1, 3
