Which equation can be used to solve for y-value of the solution in the system of linear equations below?
-6x+4y=-62 -3x-5y=-17

The value of y is (-2)

Step-by-step explanation:

To solve the linear equation, Number of unknown variables and number of equations must be same.

In given equation,

-6x+4y=-62    Equation 1

-3x-5y=-17      Equation 2

The number of Variable are 2,

So, To solve for value of y, we need to make use of two given equation and it can't be found from one single equation

Let multiply Equation 2 with 2 units

we get, -6x-10y=-34

Now, Subtracting both the equations

(-6x+4y)-(-6x-10y)=(-62)-(-34)

4y+10y=(-28)

14y=(-28)

y=(-2)

Therefore, the value of y is (-2)

i think it is c, not positive though
