If 7x + 4 = -19 + 5x, then 2x – 14 equals A) 23 B) -23 C) -3 D) 16 E) NOTA

2x-14 = -37

Step-by-step explanation:

7x + 4 = -19 + 5x,

Subtract 5x from each side

7x-5x + 4 = -19 + 5x -5x

2x +4 = -19

Subtract 4 from each side

2x +4-4 = -19 -4

2x = -23

We want to find 2x -14

2x = -23

2x-14

-23-14

-37

-37

Step-by-step explanation:

First, let's solve for x.

7x+4= -19+5x

Subtract 5x from both sides of the equation.

(7x-5x)+4= -19 (+5x-5x)

(7x-5x)+4=-19

2x+4=-19

Subtract 4 from both sides of the equation.

2x(+4-4)=(-19-4)

2x=(-19-4)

2x= -23

Divide both sides of the equation by 2.

2x/2= -23/2

x= -23/3

x= -11.5

Next, let's find what 2x-14 is equal to. Substitute -11.5 in for x.

2x-14

2(-11.5)-14

Multiply 2 and -11.5

-23-14

Subtract 14 from -23.

-37

2x-14 is equal to -37.

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

the answer is 0.3175 hope that you ^w^
