In this video we look at a method of solving linear simultaneous equations called elimination where the goal to combine the two equations into one whilst eliminating a variable. From this we can then solve the problem. (With examples).

On the last problem, i got x as -47/11 and y as 63/11. When substituting into equation 1, it came out as 33 so im confused

You can maybe try talk to a teacher or something to help you Maybe try get an app or something that can also explain it to you more easily? Maybe try search for another video?

Why multiple by 3 and when did 9 come from
@aidang4070

the multipled by three so that it would match up with the other y which is 3y so it could cancel out. SOrry if it isn't well explained
when do you add and subtract 2 and 3 because you added in the first one and subtract in the second and didnt explain

Still don't understand 😢😢
thx this helps, nice vid
Taught well but I didn't get the concept
Base on what I've learned this isn't correct or maybe it's just different numbers that u used than what I used. Cause I used 2 and 3 to get the coefficients to be equal numerically

Bcoz we have to make the 2 eqns y same as 1 so it multiply by 3 so it will become 3y and then both get cancelled

Around 3000 BCE, the Sumerians developed a numerical system based on the sexagesimal system (base 60), which is still in use for measuring time (seconds, minutes, and degrees in a circle) today. They also made strides in geometry, algebra, and arithmetic.
Why are you multiplying by 3?

Because they got the value of y in the first equation which is 3 so instead of writing y with the first equation they multiplied by 3 aka the value of y
