Solve each system by elimination. show all ! 4) 36x+12y=-12 -9x-3y=3 solution: work:

\left[x \right] = \left[ \frac{-1}{3}+\frac{ - y}{3}\right][x]=[​3​​−1​​+​3​​−y​​]

\left[x \right] = \left[ \frac{1}{3}+\frac{y}{3}\right][x]=[​3​​1​​+​3​​y​​]

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
