Answer:
a=-4, b=-4. (-4, -4).
Step-by-step explanation:
-3a+7b=-16
-9a+5b=16
-------------------
-3(-3a+7b)=-3(-16)
-9a+5b=16
---------------------------
9a-21b=48
-9a+5b=16
------------------
-16b=64
b=64/-16
b=-4
-3a+7(-4)=-16
-3a-28=-16
-3a=-16+28
-3a=12
a=12/-3
a=-4
Answer:
Step-by-step explanation:
8/11 is equal to x/20
Cross multiply
8 times 16 and 11 times x
128=11x
Divide
Then you get 11/128
Divide and simplify!!
