3 tables are 4-seated table and 4 tables are 6-seated table.
<u>Step-by-step explanation</u>:
Let us assume,
The 4 seats table be type A table and the 6 seats table be type B table.
- The number of type A seat = x
- The number of type B seat = y
- Total table rented = 7 tables
- Total people in party = 36 people
x+y = 7 --------(1)
4x+6y = 36 -------(2)
Multiply (1) by 6 and subtract (2) from (1)
6x+6y = 42
- (<u>4x+6y = 36</u>)
<u> 2x = 6 </u>
x = 6/2
x = 3
The number of 4 seated table is 3.
Substitute x=3 in (1)
3+y = 7
y = 4
The number of 6 seated table is 4.

insert each number for the x value :]
Answer:
x=17.7 y=27.4
Step-by-step explanation:
We should start with the equation with only 1 variable.
4x-4+6x+7= 180
Solve.
10x+3=180
10x=177
x=17.7
3y-20+4x-7 should equal 180.
So solve.
3y-27+4x=180
Substitute for x.
3y-27+4(17.7)=180
Solve.
3y-27+70.8=180
3y=82.2
y=27.4
I honestly don’t know. It’s beyond stressful. Ever since Bill gates decided to put in “Common Core” in schools it became harder. Common Core in my opinion is useless, It teaches us nothing where going to use in life. Its unnecessary.
