Solution:
Let the three consecutive multiples of 4 be 4x, 4(x+1) and 4(x+2)
Then we can write
![4x+4(x+1)+4(x+2)=52\\ \\ x+x+1+x+2=52/4\\ \\ 3x+3=13\\ \\ 3x=10\\ \\ x=\frac{10}{3}\\](https://tex.z-dn.net/?f=%204x%2B4%28x%2B1%29%2B4%28x%2B2%29%3D52%5C%5C%20%5C%5C%20x%2Bx%2B1%2Bx%2B2%3D52%2F4%5C%5C%20%5C%5C%203x%2B3%3D13%5C%5C%20%5C%5C%203x%3D10%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B10%7D%7B3%7D%5C%5C%20)
As 10/3 is not a multiple of 4. Hence no consecutive multiples are possible.
Answer:
No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into -4x-y=-2.
-4x -(-4x + 3) = -2
-4x + 4x - 3 = -2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.

Answer:
900
Step-by-step explanation:
The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.
Let the number of people who own a flip phone=x
If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600
To find x, we express the ratio and population as an equality.
5:3=x+600:x
Expressing the ratios as fractions would give:
![\dfrac{5}{3}=\dfrac{x+600}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B3%7D%3D%5Cdfrac%7Bx%2B600%7D%7Bx%7D)
Next, we cross multiply
5x=3(x+600)
Open the brackets by expansion.
5x=3x+(3 X 600)
5x=3x+1800
Subtract 3x from both sides.
5x-3x=3x-3x+1800
2x=1800
Divide both sides by 2
x=900.
Since x=900, the number of people who own a flip phone is 900.
