SOURCE: what ia the sulution of 3y-6x=-3
To find the solution, first find the value of y for each equation.
Then substitue one equation into the other so that you only the x variable left.
Then just solve for x.
Once you have a value for x, then you can easily solve for y.
So for the first equation:
3y - 6x = -3
3y = 6x - 3
y = 2x - 1
Now for the second equation:
2y + 8x = 10
2y = -8x + 10
y = -4x + 5
Since both equations equal y, they also equal each other, therefore:
2x - 1 = -4x + 5
Now just solve for x:
2x + 4x = 5 + 1
6x = 6
Now substitute x=1 into either original equation:
y = 2x - 1
y = 2 (1) - 1
y = 2 - 1
y = 1
Therefore the solution is x=1 and y=1
Good luck, I hope that helps.
