Here's what we know:
B = A + 12
C = B + 17 (which is A + 29)
D = C + 23 (which is A + 52)
E = 207
A + B + C + D + E = 822
.
Let's subtract Ed first.
822 - 207 = 615
The equation is now:
A + B + C + D = 615
Substitute the values from above, using the As.
A + (A+12) + (A+29) + (A+52) = 615
Add
4A + 93 = 615
Subtract 93 from each side
4A = 522
Divide each side by 4
A = 130.5
.
therefore B = 142.5, C = 159.5, D = 182.5
.
Let's add them together to prove it.
130.5 + 142.5 + 159.5 + 182.5 + 207 = 822
Success!
