Solve the system by writing it as a matrix equation and using the inverse of the coefficient

Question:

Solve the system

0.04x +0.05x2 0.04x0.05x2 x + + 0.06x3 = 360 - 0.04x3 = 120 X2 + X3 = 7,000

by writing it as a matrix equation and using the inverse of the coefficient matrix. (Before starting, multiply the first two equations by 100 to eliminate decimals. Also, see Problem 33.)
