Use addition to solve the linear system of equations.
1 answer:
Answer:
(-8, -21)
Step-by-step explanation:
Given the two equations ...
- y = 2x -5
- 3x +3 = y
you can solve them by adding the first equation to the second.
... (y) + (3x+3) = (2x-5) +(y)
... y + 3x + 3 = 2x -5 +y
Adding -y -2x -3 to both sides of the equation gives ...
... x = -8
Putting this value in the first equation gives ...
... y = 2(-8) -5 = -21
