Start by trying to find a common multiple of the last term, e.g. if you have a quadratic that ends in 4, when you factorise this function, we should get two terms ending in multiplies of 4 so (1,4) or (2,...

1) Multiply both equations so we have the same coefficient of one of the variables. This allows us to eliminate one of the variables and solve for the other. (4x + 5y = -8) --> Multiply b...

multiply both sides by 8 --> 4+x=16subtract 4 from both sides x=12

First we must identify the recurring part of the decimal. We see that 72 is repeated, hence it is the recurring part of the decimal. Next, we say x = 0.1727272..., the reason why will become apparent shor...
