Answer:
To solve the system of equations:
2x + y = 5 (Equation 1)
2y = 2x - 8 (Equation 2)
We can use substitution method. Solving Equation 2 for y, we get:
y = x - 4
Substituting this expression for y into Equation 1, we get:
2x + (x - 4) = 5
Simplifying and solving for x, we get:
3x = 9
x = 3
Substituting this value of x into Equation 1, we get:
2(3) + y = 5
y = -1
Therefore, the solution to the system of equations is x = 3 and y = -1.
To solve the system of equations:
2x + y = -4 (Equation 1)
x + y = -7 (Equation 2)
We can use elimination method. Adding the two equations together, we get:
3x = -11
x = -11/3
Substituting this value of x into Equation 2, we get:
-11/3 + y = -7
y = -7 + 11/3
y = -10/3
Therefore, the solution to the system of equations is x = -11/3 and y = -10/3.
