Help. As usual i suck at math.
Blababa [14]

Answer:

(4,6) is the solution.

Step-by-step explanation:

Given $ 4x + y = 10 $

Let the solution be $ (a,-6) $.

The solution to this line means it should satisfy the equation. Therefore, substituting this we get,

$ 4(a) - 6 = 10 $

$ \implies 4a = 16 $

Dividing by 4 throughout we get,

$ a = 4 $

Therefore, the solution is: (4,6)

6x-4y=-15 and x-4y=1
Harlamova29_29 [7]

Answer:

The solution to the given system of equations is

(-\frac{16}{5},-\frac{21}{20})

Step-by-step explanation:

Given system of equation are

6x-4y=-15\hfill (1)

x-4y=1\hfill (2)

To solve equation by using elimination method

Now subtracting equations (1) and (2)

6x-4y=-15

x-4y=1

_________________

5x=-16

x=-\frac{16}{5}

Substitute x=-\frac{16}{5}  in equation (1)

6(-\frac{16}{5})-4y=-15

-\frac{96}{5}-4y=-15

-4y=-15+\frac{96}{5}

-4y=\frac{21}{5}

y=-\frac{21}{20}

Therefore the solution is

(-\frac{16}{5},-\frac{21}{20})
