What is the solution to the system of equations? use the substitution method.
j+k=3
j-k=7

a. the solution is (8, 1)
b. the solution is (5,-2)
c. there is no solution
d. there are an infinite number of solutions.

If you would like to find the solution to the system of equations, you can do this using the following steps:

j + k = 3
j - k = 7 ... j = 7 + k

j + k = 3
7 + k + k = 3
2k = 3 - 7
2k = - 4
k = - 2

j = 7 + k = 7 - 2 = 5

(j, k) = (5, -2)

The correct result would be B. The solution is (5, -2).
