Answer:

7x + 2

Step-by-step explanation:

Original Equation: 3x − ( −2 − 4x)

First, we distribute the negative sign:

= 3x + (−1) (−2−4x)

=3x + (−1)(−2) + (−1)(−4x)

= 3x + 2 + 4x

Using the communitive property of addition, we can write:

= 3x + 4x + 2 (Instead of 3x + 2 + 4x)

Combining like terms, we get:

= (3x + 4x) + 2

= 7x + 2

Which graph represents the solution set of this inequality? -2x + 7 < 23−2x+7<23

kondaur [170]

Answer:

The graph and the number line in the attached figure

Step-by-step explanation:

we have

$-2x+7 < 23$

Solve for x

subtract 7 both sides

$-2x+7-7 < 23-7$

$-2x < 16$

Divide by -2 both sides

Remember

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$x > -8$

The solution is the interval (-8,∞)

All real numbers greater than -8

In a number line the solution is the shaded area at right of x=-8 (open circle)
