Ways of solving it
Step-by-step explanation:
20x - 5x = 65 - 5
as the numbers cross over the equality sign, their positive changes to negative and vice versa
15x = 60
Divide both side by the coefficient of X which is the number Infront of X
15x/15 = 60/15
X=4
OR
20x + 5 = 5x + 65
Dividing through by 5. All the numbers above are divisible by 5. 5 is also the LCM
4x + 1 = X + 13
4x - X = 13 - 1
3X = 12
X = 4

Answer:
The number of small and large boxes purchased are:
- 2 small boxes.
- 6 large boxes.
Step-by-step explanation:
To solve the unknowns, two equations must be established with the information provided:
- 150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)
- Y = 3X (Large boxes are triple the small ones)
Then equation 2 is replaced in equation one and variable X is cleared:
- 150X + 400 (3X) = 2700
- 150X + 1200X = 2700
- 1350X = 2700
- X = 2700/1350
- <u>X = 2
</u>
Finally, the value of X is replaced in equation 2 to find the number of large boxes:
- Y = 3X
- Y = 3 (2)
- <u>Y = 6</u>
