Morgan is arranging a bowling party for his friends. the party room at the
bowling alley is $35. the bowling alley also charges $13 for each person who
attends the party. what is the maximum number of people that morgan can
invite to stay under his budget of $175?
identify the inequality to solve and the maximum number of people.

First, let's find y by substituting x for what x is equal to, so that we will only have one variable and we can solve the equation.

x = y     given
x - 3y = 4     given
y - 3y = 4   substitute x for y, because x = y
-2y = 4     subtract
y = -2   divide

now, to find x, we need to substitute our value for y back into the original equation.

x = y
x = -2   substitute -2 for y, since y = -2

the correct answer is (-2,-2).

hope this !

If x = y then put x where y is or y wherever x is.
x-3 x=4
-2x = 4
x = -2

now plug that in to find y
x-3y = 4
-3y = 4+2
-3y = 6
y = -2
