Answer:
(-2,8)
Step-by-step explanation:
8x + 9y=56
-9x + y = 26
---------------------------------------------------------------------------------
-9x + y = 26
+9x = +9x
y = 9x + 26
---------------------------------------------------------------------------------
8x + 9(9x+26) = 56 <-- substitute for y from above
8x + 81x + 234 = 56
89x + 234 = 56
- 234 = - 234
89x = - 178
x = -2 <--- we got the x value!!
--------------------------------------------------------------------------------
-9x + y = 26
-9 (-2) + y = 26 <-- substitute for x from above
18 + y = 26
- 18 = - 18
y = 8 <-- we got the y value!!

Hi well you didn’t tell me weather your adding them, subtracting, dividing, or multiplying. So here is the answer for all 4 of them. Adding them you get 1261.8, subtracting then you get -43.8, multiplying them you get 397555.2, and dividing them you get 1015/1088. If you just need the answer for each one (5.8x105) is 609 and (6.4x102) is 652.8. Hopefully I helped in some type of way. Have a good night :)
