The value of the variable x at y = 15 will be 200.
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equation is given below.
(1/5)x - (2/3)y = 30
Solve the equation for x, then we have
(1/5)x = 30 + (2/3)y
x = 150 + (10/3) y
The value of the variable x at y = 15 will be
x = 150 + (10/3) × 15
x = 150 + 50
x = 200
The value of the variable x at y = 15 will be 200.

Please someone help
Answer:
The highest common factor would be 114
3876 = 2x3x3x17x19
114 = 2x3x19
The highest common factor (HCF) of 3876 and 114 is 6.
To find the highest common factor (HCF) of two numbers, such as 3876 and 114, we need to determine the largest number that divides evenly into both given numbers.
We can start by finding the prime factors of each number. The prime factorization of 3876 is 2 × 3 × 1,29, and the prime factorization of 114 is 2 × 3 × 19.
The common factors we can identify are 2 and 3, so the HCF of 3876 and 114 is 2 × 3, which is 6.

Answer:
The solution would be (6, -11)
Step-by-step explanation:
In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.
x = -2y - 16
x = -2(-3x + 7) - 16
x = 6x - 14 - 16
x = 6x - 30
-5x = -30
x = 6
Now that we have the value of x, we can find the value of y.
y = -3x + 7
y = -3(6) + 7
y = -18 + 7
y = -11
Answer:
Here is the break down of the answer x=6 and y=-11
Step-by-step explanation:
4r-7r +8+ r
Answer:
-2r+8
Step-by-step explanation:
4r-7r+8+r
5r-7r+8
-2r+8
-2r+8
The first step is to combine like terms. These would be 4r, -7r, and r since they have the same variable. This gives you -2r. Since there are no other like terms to combine, you end up with -2r+8
