It should be 2x-156 if that’s not it then i have no clue
1st: do distributive property, that will give you 3x + 6 + 5x
2nd: combine like terms to simplify, this will give you 6 + 8x
the answer is 60.75 you had to multiply then add
For the each of them simply substitute for x in each equation to see if you get the corresponding y , it doesnt really get any more straightforward than this
132 + 146 + c should be greater than or equal to 325, and c should be greater than or equal to 47.
