Answer 2

Solving the System of Equations

To find the values of a and b for which the system has a solution with x=3 and y=-1, we can use the given system of equations:

3x - 5y = a 2x + y = b

By substituting x=3 and y=-1 into the equations, we can solve for a and b.

Substituting x=3 and y=-1 into the equations gives:

3(3) - 5(-1) = a 2(3) + (-1) = b

Solving these equations gives:

a = 14 b = 5

Therefore, the system has a solution for a=14 and b=5.
