3. What is the solution to the equation 5x + 7 + 2 x = 7(2x + 3) - 63?
Scrat [10]

Step-by-step explanation:

5x+7+2x=7(2x+3)-63

We move all terms to the left:

5x+7+2x-(7(2x+3)-63)=0

We add all the numbers together, and all the variables

7x-(7(2x+3)-63)+7=0

We calculate terms in parentheses: -(7(2x+3)-63), so:

7(2x+3)-63

We multiply parentheses

14x+21-63

We add all the numbers together, and all the variables

14x-42

Back to the equation:

-(14x-42)

We get rid of parentheses

7x-14x+42+7=0

We add all the numbers together, and all the variables

-7x+49=0

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

-7x=-49

x=-49/-7

x=+7 - Answer
