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

Rufina [12.5K]

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 :^)

1 2/5m - 3/5 ( 2/5m + 1 )

Hunter-Best [27]

Answer:

1 4/25 - 3/5, or 29/25 - 3/5, or $\frac{(29m - 15)}{25}$

it doesn't really matter they all mean the same

Step-by-step explanation:

1 2/5m - 3/5(2/5m + 1)

multiply first

1 2/5m - 6/25m - 3/5

multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.

1 10/25m - 6/25m - 3/5

add/subtract

1 4/25m - 3/5
