Solve algebraically 8x + 10y = -4 -4x = 2 + 5y

Mathematics
1 answer:
Rufina [12.5K]3 years ago
8 0

The answer to the first one is:

x=-5/4y+-1/2. Why? 

 In the equation 8x+10y=-4, you subtract 10y form each side which leaves you with 8x=-10y-4. Right? Then you divide each side by 8 which gives you the answer

The answer to the second one is the same answer to the first problem. Why? Because you can already divide each side which gives you x=-5/4y+-1/2.

Hope this helps :^)
