i need to find the matrix of T

i know that T is of 2X4 size

so i built T as

a1 a2 a3 a4

b1 b2 b3 b4

and multiplied by the given vector

i built a matrix for "a" parameters and "b" parameters

but i got only 3 equation instead of the needed 4

in order to get the values of "a"'s and "b"'s

how to use the independent vectors data to construct the 4th equation??
