Question

OK LAST ONE THANK YA JESUS!!!!!!!!!!
Circle the error and Explain why it is an error.
Given
5( 8 – 3x) = 5x + 70
Step 1: Distribute
40 – 15x = 5x + 70
Step 2: Subtraction property of Equality
-30 -15x = 5x
Step 3: Addition property of Equality
-30 = 10x
Step 4: Division Property of Equality
-3 = x
Step 5: Identity property
x = -3

Answer 1

I think 3 or 2 might be wrong

Answer 2

and then i have to explain why but i don't know yet

Answer 3

yep step 3 is wrong....using addition property is still correct but they added incorrectly

Answer 4

oh ok

Answer 5

is that all

Answer 6

yep

Answer 7

wait so were they suppose to add 30 and 10

Answer 8

and get 40 or somethin

Answer 9

hmm no step 3 is being applied to statement
-30 - 15x = 5x

Addition property allows for adding 15x to both sides
However, 5x +15x = 20x

Resulting in:
-30 = 20x

Answer 10

OH ok

Answer 11

YET AGAIN THANK YOU!
