Answer:

x = 0

Step-by-step explanation:

First, multiply the -3 by two (<u>-3</u>(x + 2)<u>2</u> + 4 = -8) -- -6(x+2)+4 = -8.

Then, subtract 4 from both sides (-6(x+2)+<u>4</u> = -8) -- -6(x+2) = -12

After that, divide both sides by -6 (<u>-6</u>(x+2) = -8) -- \frac{-6\left(x+2\right)}{-6}=\frac{-12}{-6}

Simplify -- x+2=2

Subtract 2 from both sides (x+<u>2</u>=2) -- x = 0

Hope this helped! Good luck with future math problems :)

What is the solution to the expression Negative 2 minus 3 minus (negative 4)? A number line going from negative 10 to positive 1
beks73 [17]

The solution of the expression is -1 ⇒ 3rd answer

Step-by-step explanation:

Let us revise some important rules on the number line

  • If we add number to another number we move to right
  • If we subtract a number from another number we move to left

∵ The expression is negative 2 minus 3 minus (negative 4)

∵ negative 2 = (-2)

∵ minus means (-)

(-2) minus 3 means move 3 units from (-2) to left, so you will pass -3, -4, and stop at -5

∴ (-2) - 3 = -5

∵ minus (negative 4) = - (-4)

- Remember (-)(-) = (+)

∴ minus (negative 4) = + 4

That means move 4 units to the right from -5, then you will pass -4, -3, -2, and stop at -1

∴ -5 + 4 = -1

∴ The expression (-2) - 3 - (-4) = -1

The solution of the expression is -1
