-(5x-4y=7) <--- Multiply by a negative so that y can cancel out
4x-4y=12
=-5x+4y=-7
4x-4y=12
=-x=5
x=-5
5(-5)-4y=7 <--- plug x back in to solve for y
-25-4y=7
+25 +25
-4y/-4=32/-4
y=-8

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
