Final answer:
To solve the system using substitution, substitute one equation into the other to eliminate one variable. The substituted equation is x = -5 and y = 11.
Step-by-step explanation:
To solve the system using substitution, we need to substitute one equation into the other to eliminate one variable. Given the system of equations:
y = -x + 6
x + 2y = 17
Let's solve the first equation for x:
x = -y + 6
Substitute this value of x into the second equation:
-y + 6 + 2y = 17
Simplify the equation:
y + 6 = 17
Subtract 6 from both sides:
y = 17 - 6
y = 11
Now substitute this value of y back into the first equation to find x:
x = -11 + 6
x = -5
Therefore, the substituted equation is x = -5 and y = 11.
