I've been looking on youtube to try and learn how to do these more complex equations but all the examples use small numbers that easily fall into place.

Ive got

Equation One: 48A - 32B - 2C = 0

Equation Two: -32A +46B - 11C = 0

Equation Three: -2A - 11B + 13C = 54

Ive mulitplied equation three by -16 which gives me:

NewThree: 32A + 176B - 208C = -864

Then I added equations Two and NewThree:

Equation Two: -32A + 46B - 11C = 0

NewThree: 32A + 176B - 208C = -864

Which cancelled out the 32A and gave me:

222B -219C = -864

I then took Equation Three and mulitplied it by 24 which gave me:

Anothernewthree: -48A - 264B + 312C = 1296

Then added Equation One and Three together:

Equation One: 48A - 32B - 2C = 0

Anothernewthree: -48A - 264B + 312C = 1296

Which cancelled out the 48A leaving me with:

-296B + 310C = 1296

Which left me with:

222B -219C = -864

-296B + 310C = 1296

And it's at this point that I get stuck :/

Is this the best route to take? Is there another method that is better to take for these larger numbers? The examples on youtube use examples that have small numbers and are easily solved, but I don't know what step to take next for this one :/

If anyone could help me I'ld be very grateful
