Answer:

x=12

Step-by-step explanation:

5(x-8) + 15 = 35

<em>First remove the parenthesis by multiplying</em>

5x-40 + 15 = 35

<em>Add -40+15</em>

5x -25 = 35

<em>Add 25 to both sides</em>

5x=60

<em>Divide both sides by 5</em>

x=12

Now you can plug in 12 for x if you need to, it will equal 35

<h3>Given Equation:</h3>

\boxed{ \sf5(x - 8) + 15 = 35}

<h3>Step-by-step explanation:</h3>

\hookrightarrow\sf5(x - 8) + 15 = 35

Multiply 5 by x - 8

\hookrightarrow\sf5x -40 + 15 = 35

Now after multiplying 5 with x-8 we get 5x - 40

Now add -40 with 15

\hookrightarrow\sf5x -25= 35

After adding-40 with 15 , we get -25.

Now transfer-25 to other side

\hookrightarrow\sf5x = 35 + 25

After transferring -25 to other side it's sign changes and from -25 it changes to +25.

Now add 35 with 25.

\hookrightarrow\sf5x =60

After adding 35 with 25 , we get 60.

Now transfer and then divide 5(denominator) with 60.

\hookrightarrow\sf{}x = \dfrac{60}{5}

Now Divide 5 with 60.

\hookrightarrow\sf{}x = \cancel\dfrac{60}{5}

\\

\hookrightarrow\sf{}x =12

After dividing 55 and 5 , we get our final answer i.e. value of x as 12.

<h3>Verification:</h3>

➻5(x - 8) + 15 = 35

put value of x in this equation

➻5(12 - 8) + 15 = 35

Now by following the <u>BODMAS</u> rule , first we will solve the expression inside the bracket.

there fore first subtract 12 with 8

➻5(4) + 15 = 35

After subtracting 12 with 8, we get 4.

Now multiply 4 with 5.

➻20+ 15 = 35

After multiplying 4 with with 5 we get owr product as 20

Now add 20 with 15.

➻35 = 35

After adding 20 with 15 we get owr sum as 35.

Now as we can see :

LHS = RHS

Hence verified!

.°. <u>owr final and verified value of x is 12.</u>

Dawn has been using two bank accounts to save money for a car. the difference between account 1 and account 2 is $100. if she us
asambeis [7]
1) name the variables:

 - amount in account 1 "a"
 - amount in account 2 "b"

2) trtanslate the statements into equations:

<span>- the difference between account 1 and account 2 is $100.

=> a - b = 100

-  if she uses 3/8 of account 1 and 7/8 of account 2, Dawn will have a down payment of $2,000.

=> (3/8)a + (7/8)b = 2000

3) solve the system of equations

(1) a - b = 100
(2) (3/8)a + (7/8b) = 2000

Steps:

- multiply equation (1) by 7 and equaton (2) by 8

=>

(1) 7a - 7b = 700
(2) 3a + 7b = 16,000

- add the two equations

=>

7a + 3a - 7b + 7b = 700 + 16,000

- combine like terms:

10a = 16,700

- divide by 10:

a = 16,700 / 10 = 1670

- use equation (1) to find b:

a - b = 100 => b = a - 100 = 1670 - 100 = 1570

Answer: Dawn has $ 1670 in account 1 and $ 1570 in account 2. </span>
