What is the solution to 4(y-3)+19=8(2y+3)+7

Mathematics
1 answer:
Effectus [21]3 years ago
3 0

Answer:

Y = -1.2 OR - 1 1/5

Step-by-step explanation:

4(y-3)+19=8(2y+3)+7      First, simplify the problem by multiplying the numbers outside of the ()’s by the numbers inside the ()’s

4y-12+19=16y+24+7       Next, simplify again by combining like terms (EX: -12 + 19 = 7)

4y+7=16y+31.                 Then, get Y by itself.

-4y     +4y

7=20y+31

-31        -31        

-24=20y.                         (Divide to get Y by itself)

/20  /20              

-1.2 = Y or - 1 and 1/5 = Y

vodka [1.7K]

Let be "x" the number of colored pencils in the box.

According to the information given in the exercise, there are 84 pencils in the box and 53 of them are regular pencils.

Knowing this information, you can set up the following equation:

x+53=84

Finally, you have to solve for the variable "x" in order to find its value. In order to do this, you can apply the Subtraction property of equality by subtracting 53 from both sides of the equation:

\begin{gathered} x+53-(53)=84-(53) \\ x=31 \end{gathered}

The answer is: There are 31 colored pencils in the box.

Brilliant_brown [7]

Answer:

The best option is c

Step-by-step explanation:

The same textbooks contains a total of 848 pages . Which represent the total number of pages , y , of any number of the same textbooks , x.

The number of same text book = x

Each of this textbook contains a total of 848 pages .

The total number of pages can be computed as

y = 848x

for 4 same text book

y = 848 × 4 = 3392 pages

for 3 same text book

y = 848 × 3= 2544 pages

for 7 same text book

y = 848 × 7 = 5936 pages

for 8 same text book

y = 848 × 8 = 6784 pages

for 11 same text book

y = 848 × 11 = 9328 pages
