Answer:
Step-by-step explanation:
Equation
5y = 3y + 4
combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.
-3y + 5y = 4
After adding a low negative to a high positive number. Turns into 2y.
2y = 4
Divide 2 on both sides to remove the number from the variable on the left.
y = 
2 is canceled on the left side which gives the solution for Y.
y = 2
After applying formula and calculations it is round about <span>28.3</span>
B
Changing the order does not change the result of the equation
Answer:
n = 1
Step-by-step explanation:
Add 20 to both sides, obtaining
n = 4 - 3n
Next, add 3n to both sides:
4n = 4
Finally, solve for n by dividing both sides by 4:
n = 1
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes
