2(10 - 13) = -34 + 60
20 - 26 = -34 + 60 (distribute)...correct
-26 = -34 + 40 <=== here it ishe added 20 instead of subtracting 20...he should have used the subtraction property

Mathematics

2(m + 2) = 22

2(m) + 2(2) = 22

2m + 4 = 22

2m = 22 - 4

2m = 18

2m / 2 = 18 / 2

m = 9

To distribute the 2 to each term inside the parentheses means to multiply the 2 by both terms in the parentheses so

2(m + 2) means (2 × m) + (2 × 4)

Circle the step where the error has occurred. explain why it is an error.

given: 2(10−13)=−34+60

step 1: distribute
20−26 = −34+60

step 2: addition property of equality
−26 = −34+80

step 3: addition property of equality
8=80

step 4: division property of equality
=10
