A system of equations has 1 solution. If 4x – y = 5 is one of the equations, which could be the other equation? y = –4x + 5
y = 4x – 5
2y = 8x – 10
–2y = –8x – 10

Someone this asap for a group of students attends a basketball game. * the group buys x hot dogs at the concession stand for $2 each. * the group buys y drinks at the concession stand for $3 each. the group buys 29 items at the concession stand for a total of $70. how many hot dogs did the group buy?

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.

Aye asap pls ! markin da brainiest too ! btw da step choices are all add, distribute, divide, n subtract
