Which expression is equivalent to 486 – 9 + 6 + 33 × 2? a . [(486 – 9) + (6 + 33)] × 2 b . 486 – [(9 + 6 + 33) × 2] c . (486 – 9) + 6 (33 × 2) d . (486 – 9 + 6) + (33 × 2)

If you would like to find the equivalent expression to 486 – 9 + 6 + 33 × 2, you can do this using the following steps:

486 – 9 + 6 + 33 × 2 = (486 – 9 + 6) + (33 × 2) = 483 + 66 = 549

The correct result would be D. (486 – 9 + 6) + (33 × 2).

Expression equivalent to 486 – 9 + 6 + 33 × 2 will be :

486 – 9 + 6 + 33 × 2 = (486 – 9 + 6) + (33 × 2)

Proof :
Solving both sides by DMAS rule,

486-9+6+66 = 483+66
477+6+66=549
549=549

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
