Which pair shows equivalent expressions? 2x+10=-20x-5) -2(x+5)=2x-10 -2x-10=-2(x+5) -2(X-5)=-2x-10

the awnser is 15 my

x = 1/2 thus Line 3 is false

Step-by-step explanation:

Solve for x:

10 - 2 x = 14 x + 2

Hint: | Move terms with x to the left hand side.

Subtract 14 x from both sides:

10 + (-2 x - 14 x) = (14 x - 14 x) + 2

Hint: | Combine like terms in -2 x - 14 x.

-2 x - 14 x = -16 x:

-16 x + 10 = (14 x - 14 x) + 2

Hint: | Look for the difference of two identical terms.

14 x - 14 x = 0:

10 - 16 x = 2

Hint: | Isolate terms with x to the left hand side.

Subtract 10 from both sides:

(10 - 10) - 16 x = 2 - 10

Hint: | Look for the difference of two identical terms.

10 - 10 = 0:

-16 x = 2 - 10

Hint: | Evaluate 2 - 10.

2 - 10 = -8:

-16 x = -8

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -16 x = -8 by -16:

(-16 x)/(-16) = (-8)/(-16)

Hint: | Any nonzero number divided by itself is one.

(-16)/(-16) = 1:

x = (-8)/(-16)

Hint: | Reduce (-8)/(-16) to lowest terms. Start by finding the GCD of -8 and -16.

The gcd of -8 and -16 is -8, so (-8)/(-16) = (-8×1)/(-8×2) = (-8)/(-8)×1/2 = 1/2:

x = 1/2
