Answer:
(- 1, 9 )
Step-by-step explanation:
One of the equations gives y = 9, the y- value
To find the value of x, substitute y = - 3x + 6 , that is
- 3x + 6 = 9 ( subtract 6 from both sides )
- 3x = 3 ( divide both sides by - 3 )
x = - 1
Solution is (- 1, 9 )
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
