write a system of equations and solve
Solve the system of equations x-2y+3z = 13 2x+y+z = 1 -3x+2y-2z = -13
x-y+3z=-1 5x+z=0 x+4y+z=4
3a-12b=-6 6a+40c=32 24b+30c=38
x+2y-z=-12 2x+7y+4z=-33 x+3y+z=-15 section 3.3.13
x-y=4 4x-3z=28 4y+z=12 Section 3.3. 6
6x+y+6z=6 7x-y+5z=7 x-2y-z=0 section 3.3. 5
6x+y+6z=6 7x-y+5z=7 x-2y-z=0 Section 3.3. 5

A mixture contains one cup of almonds for every three cups of popcorn. One cup of nuts costs $1.82 and one cup of popcorn costs $3.50. Ann purchased a total of $308.56 worth of mixture. How much of...
3x + 4y + z = 7 2y + z = 3 -5x + 3y + 8z = -31 thanks
solve the system of equations 3x + 4y + z = 7 2y + z = 3 -5x + 3y + 8z = -31 I have...
5/4x - 4/3y + 5/4z = 6 5/16x + 5/4y - 4/16z = -4 3/4x - y +3/4z = 6
x-3y+4z=13 2x+y+z=-2 -2x+3y-3z=-10
Did I solve these correctly? 1. 5x - 2y = -24 - 4y = -48 - 10x = 5x - 2y = -24 ...
did I solve this correctly? 3x + y = 7 3x + y = 10 (mulitply by -1) = -1(3x + y) = -1(10) = ...
