Step 1 associative property
step 2 subtract 2x from both sides
step 3 add 28 to both sides
step 4 divide 2 on both sides
Answer:
The number is 21.
Step-by-step explanation:
First you need to solve for n.
So the equation would be 2n = |5n-63|
First you'd subtract 5n from each side, that would give you -3n=|-63|
Then you need to divide each side by -3 to get n=21.
~~~~~
To check, you can just plug 21 back into the equation.
2(21) = |5(21) - 63|
42 = |105-63|
42 = |42|
42 = 42
I'm not 100% sur what it is asking but I think the expression would be
