Answer:
The solution to the system of equations is:
a = -1
b = 6
Step-by-step explanation:
Given the system of equations:
a = -b + 5 .............................................................(1)
2b + a = 11 ............................................................(2)
Substituting the expression for a in equation (1) into equation (2), we have:
2b + (-b + 5) = 11
2b - b = 11 - 5
b = 6
Using this value of b in equation (1), we have:
a = -6 + 5
= -1
Therefore,
a = -1
b = 6
