I want The solution method in matlab

Solve for x and t the following equations: (Need code and the x,t values): 1) Suppose a partial moves a long x-axis according the following equation x+4t=22x+6t=4 Where x is the displacement of the partial (meter), t is the time Of particle during move to the displacement x : a) Determine the coefficient matrix. b) Find invers the coefficient matrix and name it z. c) Find the displacement x and t from function. e) Plot a graph of (t,x) name it (Displacement-Time Graph), with a grids and x-axis labels. f) Explain the graph of the particle
