The answer is C because 6x and 6 are both in the line
<span>2x-3y=18
when x = 3
2(3) - 3y = 18
6 - 3y = 18
-3y = 12
y = -4
so(3, -4) is the solution

<h3>What is Algebra?</h3>
Algebra is a branch of mathematics that deals with symbols or variables and uses arithmetic operations (+, –, ×, ÷) to find the unknown quantities represented by these variables.
Given expression :
(-5)*(-5)*(-5)*(-5)*y*y*y*y
= 
= 
Hence, (-5)*(-5)*(-5)*(-5)*y*y*y*y =

#SPJ1
City code says you need to have a total of at least 54 toilet stalls, but each bathroom can only have 6 stalls.
So, Let the number of bathrooms to be built be = x
Number of toilet stalls needed = 54
Number of stalls each bathroom can have = 6
So, the number of bathrooms to be built are =



Hence, one must build 9 bathrooms with 6 stalls each.
Answer:
C. (7, –3)
Step-by-step explanation:
5x+6y=17
-10x-9y=-43
Multiply the first equation by 2
2(5x+6y)=17*2
10x +12y = 34
Add this equation to the second equation to eliminate x
-10x-9y=-43
10x +12y = 34
---------------------
3y = -9
Divide by 3
3y/3 = -9/3
y = -3
Now we need to find x
5x+6y = 17
5x +6(-3) = 17
5x-18 = 17
Add 18 to each side
5x-18+18 =17+18
5x =35
Divide by 5
5x/5 = 35/5
x =7
