Answer:
d = 359, j = 536
Explanation:
j + d = 895
j = d + 177
Let us substitute the second equation into the first one for j.
So the first equation can be rewritten as (d + 177) + d = 895
=> 2d + 177 - 177 = 895 - 177
=> 2d = 718
=> 2d/2 = 718/2
=> d = 359
=> j = 359 + 177
=> j = 536
Checking your answer:
j + d = 536 + 359 = 895
