Answer:
All real numbers
Step-by-step explanation:
Solve a system of equations by elimination
With the equation given, you can solve for y to get: y = x -
Then, substitute this value in on the equation.
x - 5(x - ) = 6
x - x + 6 = 6
6 = 6
The solution is all real numbers
Answer:
n = 4
Step-by-step explanation:
Given
10n + 2 = 7n + 14
Collect terms in n on the left side and numbers on the right side
Subtract 7n from both sides
3n + 2 = 14 ( subtract 2 from both sides )
3n = 12 ( divide both sides by 3 )
n = 4
It would be 3,600 - 30 = 3570
