Write an equivalent expression for 8(3+5x)+7x+4 if x=3 is the solution to both expressions the same(show work and you)

This expression 28+47x = 8 (3+5X)+7X+4.

Step-by-step explanation:

Given : Expression for 8 (3+5X)+7X+4 if X=3 .

To find : Write an equivalent expression .

Solution : We have  8 (3+5X)+7X+4.

Lets replace all the x's with 3 so we get: 8*(3+5*3)+7*3+4.

Remove the parenthesis and we get: 8*18+7*3+4.

Finally we have = 169.

To get  equivalent expression :

First distribute 8 among 3+5x and we get:

                                 24+40x+7x+4.

Now we combine all like factors and get: 28+47x.

Lets replace all the x's with 3 so we get: 28+47*3

                                      = 169 .

Therefore , This expression 28+47x = 8 (3+5X)+7X+4.
