A system of2 equations in 4 unknowns {:1 , 2:2, :53 and :4] was expressed as an augmented matrix, and was reduced using elementary row operations to give the augmented matrix shown below. Give the solution of the system. (1 3 I] 2 1D) t] t] 1 2 T For your solution, if parmeters are required, set the parameters from the last variable to the first variable, and use the parameters r, x, r {as required and in the order given]. Give aH solutions exactly {as whoie numbers or fractions}. If there is no solution, enter r'no solution" (using all lowercase letters, and without quotation marks} for each of the varia bfes. 21=| poo z2=| _om as=| jam 34: EB
