Simplify the given expression.
5+ (7 - 2) +62
5+ (7 - 2) +62 = 0

Answer 1

Answer:

1. The expression would be written as $4x-5=3x+9$ and the missing number is 14
2. $72=0$ which is false meaning there is no solution

Step-by-step explanation:

Let's say our variable for the missing number is x

Four times a number minus 5 would be written as 4x-5

Three times the number plus nine would be written as  3x+9

So the equation would be written as $4x-5=3x+9$

To solve we add 5 to both sides

$4x-5=3x+9\\+5=+5$    

$4x=3x+14$

Now we subtract 3x from both sides

$4x=3x+14\\-3x=-3x$

$x=14$

To simplify $5+ (7 - 2) +62 = 0$ we first get rid of the parentheses and rewrite the expression as $5+7-2+62=0$

You first add 5 + 7 = 12

Then subtract 12 - 2 = 10

Then add 10 + 62 = 72

So 72 = 0 which is false meaning there is no solution
