Given the statement:

(-2x + 2) subtracted from (-7x -9)

Find the expression which represents the statement in simplest terms.

Solution:

In order to find the expression, we simply equate the statement in numerical terms and we combine similar expressions.

= ( -7x -9) - (-2x + 2)

We've used the operation of subtraction, since it require the two numbers to be subtracted.

= -7x - 9 + 2x - 2

= -5x -11

In order to find the value of x, simply transpose -5x on the other side of the equation, note that when transposing a number, the sign changes. After transposing, divide both sides by 5 to find the value of x.

= -5x - 11

5x = -11

x = -11/5

Final answer:

Simplest form: -5x -11

Value of x: -11/5
