1. The problem statement, all variables and given/known data Vector a1 + vector a2 = 5*vector a3 Vector a1 - vector a2 = 3*vector a3 Vector a3 = 2i + 2j (i and j are the vector components) Express 1) vector a1 and 2) vector a2 in unit vector notation 2. Relevant equations Vector R = Ax + Yx 3. The attempt at a solution I took the first equation and replaces the a3 with 2i+2j, so vector a1 + vector a2 = 5(2i + 2j) a1 + a2 = 10i + 10j I solved for R and found direction, but I do'nt believe that helps at all. (R = sqr root of 200 and direction was 45 degrees). From the first equation with addition, I could conclude that vector a1 could equal = 10i +0j and vector a2 could equal 0i + 10j. However, these values don't work for the second equation with the subtraction. Is there some sort of secret to this problem?
