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:
x = ± 2
Step-by-step explanation:
Given
x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )
0 = 2x² - 8 ( add 8 to both sides )
8 = 2x² ( divide both sides by 2 )
4 = x² ( take the square root of both sides )
x = ±
= ± 2
