Equation: -16-7(2a+3)=23-2a

Answer: -5

Step by Step Explanation:
-16-7(2a+3)=23-2a distributive prop
-16-14a-21=23-2a add common factors
-37-14a=23-2a add 37 to both sides
-14a=60-2a add 2a to both sides
-12a=60 divide -12 from both sides

Answer:

a=-1.5 (lmk if im incorrect)

Step-by-step explanation:

-16 - 7(2a + 3) = 23 - 2a

-16-(14a+21)=23-2a

5-14a=23-2a

5=23+12a

-18=12a

-18/12 is -1.5

If one number is five more than another number, and the smaller number is half of the larger number, what are the two numbers?
Ymorist [56]

Answer:

<h2>Larger number = 10</h2><h2>Smaller number = 5</h2>

Step-by-step explanation:

Let larger number be x

Let smaller number be y

x = 5 + y---> equation (i)

y =  \frac{1}{2} x

x = 2y-----> equation (ii)

Equate equation (i) and (ii),

5 + y = 2y

Move variable to L.H.S and change its sign:

Similarly, Move constant to R.H.S and change its sign

y - 2y =  - 5

- y =  - 5

The difference sign (-) will be cancelled on both sides

y = 5

Putting the value of y in equation (ii) in order to find the value of X ( larger number)

x = 2y

Plug the value of y

= 2 \times 5

Calculate the product

= 10

Hence,

Smaller number = 5

Larger number = 10

Hope this helps..

Best regards!!
