Question

Solve for x: 5(x-2)+7=65-4(5x-8) SHOW STEPS PLZZZZZZ HELP

Answer 1

5(x-2)+7=65-4(5x-8)

We move all terms to the left:

5(x-2)+7-(65-4(5x-8))=0

We multiply parentheses

5x-(65-4(5x-8))-10+7=0

We calculate terms in parentheses: -(65-4(5x-8)), so:

65-4(5x-8)

determiningTheFunctionDomain

-4(5x-8)+65

We multiply parentheses

-20x+32+65

We add all the numbers together, and all the variables

-20x+97

Back to the equation:

-(-20x+97)

We add all the numbers together, and all the variables

5x-(-20x+97)-3=0

We get rid of parentheses

5x+20x-97-3=0

We add all the numbers together, and all the variables

25x-100=0

We move all terms containing x to the left, all other terms to the right

25x=100

x=100/25

x=4

Answer 2

Answer:

x=4

Step-by-step explanation:

1) Expand each side: 5x-10+7=65-20x+32

2) Move x to one side: 25x-10+7=65+32

3) Move everything else to other side: 25x= 65+32+10-7

4) Simplify: 25x=100

5) Solve for x by dividing both sides by 25: x=4
