How do you solve #Ax=B# given #A=((2, 3))# and #B=(4)#? Precalculus Matrix Row Operations Solving a System of Equations Using a Matrix 1 Answer Cesareo R. Sep 29, 2016 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.
