You should mention in the beggining that a, b and c are all integers. In theory, to solve for 3 variables, we need 3 equations. As we have only 2 equations here, the fact that they are all integers is the missing piece of information needed to construct a third relationship (or two possible third relationships in this case). That's how we were able to solve this.

At 7:09 man you wrote *a + 1 = c* which was wrong. so *‘c’* was valued *674* rather it would’ve been *a - 1 = c* here the actual value of *'c’* will be 672 as *a = 673* (in the second part)

Nice video! Is it possible to solve this pair of simultaneous equations with matrices?
