Answer:
Should have worked out brackets first then kept it to two subtractions (one being negative number total and the other being positive total number at step 3 ) taking you to step 4 as finish to just add the two numbers a( - 5.3) + (5.5) = 0.2
Step-by-step explanation:
(3.9 − 9.4) − 0.6 + 6.1. To simplify do brackets first so the first error was Step 2 line we show (3.9 − 9.4)− 0.6 + 6.1 below = to (-5 .3) − 0.6 + 6.1 Then to simplify Step 3 line there was a second error as 3.9 was never a simplification of the brackets and here is how it should be ( - 5.3) − 0.6 + 6.1 = ( - 5.3) + (5.5) = ( - 5.3) + (5.5) Then to simplify Step 4 line we wont need a step 5 and are left to just add the two numbers ( - 5.3) + (5.5) = 0.2
