Description

All questions on papers (linear equation problems) need to be answered and some of them need to have a check to proof that answers are correct.

Question 3b is included the numbers that need to be used.( a=2,b=2, c=8, d=3 ).

I need the answers in 2 days Max.

Due at 1120 on 20190529 2019 Summer I Math 270 Exam 1B Take Home 6 (1b) Solve the following system of equations for w,x, y, and z in R4, by row- reduction and check by substitution that your solution is correct. Show the work for row-reduction on the facing side. 2 (i) (1) ew + fx + gy + hz = e + f +g+h (2) fw + gx + hy + ez = e + f +g+h (3) gw + hx + ey + fz = e + f +g+h (4) hw + ex + fy + gz = e + f +g+h Rewrite the problem below using your values of a, b,c, and d.
