Question

PLEASE HELP ME










Solve, using the substitution method.

j + k = 3
j – k = 7

The solution is (8, 1)
The solution is (5, –2)
There is no solution.
There are an infinite number of solutions.

Answer 1

B. The solution is (5, 2)

Answer 2

solve j – k = 7 for j

j – k = 7

j – k+k = 7+k

j = 7+k

Answer 3

then plug j = 7+k into the first equation j + k = 3

j + k = 3

7+k + k = 3 ... notice how i replaced j with 7+k

solve for k
