Question

How do you solve `Ax=B` given `A=((2, 3))` and `B=(4)`?

Answer 1

See below.

Explanation:

Supposing that `x = ((x_1),(x_2))` such that

`A cdot x = 4` this will give us a line in `RR^2` of possibilities, for all the values for `x_1,x_2` such that

`2 x_1 + 3 x_2 = 4`

will be a solution.
