if `A=[{:(1,2),(3,4):}]`, `B=[{:(3,8),(7,2):}]` and 2X+A=B then find X

IF A=[{:(1,2),(3,4):}],andB=[{:(3,8),(7,2):}] and 2X+A+B then find X.

If A = [(1,2),(3,4)], B = [(3,8),(7,2)] 2X + A = B then find X.

If A=[(2,-1),(3,1)] and B=[(1,4),(7,2)] , find 3A-2B .

If A=((1" "2)/(3" "4)),B=((3" "8)/(7" "2))and2X+A=B, then find X.

If A= [(2,-1),(3,1)] and B = [(1,4),(7,2)] ,find 3A - 2B.

If A=[{:(2,-3),(4," "5):}]" and "B=[{:(-1,2),(0,3):}] , find a matrix X such that A+2B+X=O.

If g(x)=[(1,1),(2,3),(3,5),(4,7)] is a function from A={1,2,3,4} to B={1,3,5,7} and g(x)=ax+b, then find "a" and "b"?

If 2X+[(1,2),(3,4)]=[(3,8),(7,2)] , then the matrix X is equal to -

If A = [(8,0),(4,-2),(3,6)] and B = [(2,-2),(4,2),(-5,1)] , then find the matrix X, such that 2 A + 3 X = B.
