To solve for x in the equation x/(-5) = -6, you should multiply both sides of the equation by -5.
If 2x=−4
, then what is the value of 8x
?
If 2x = -4, then we can solve for x by dividing both sides of the equation by 2:
(2x)/2 = (-4)/2
x = -2

To find the value of 8x, we can substitute x = -2 into the equation:
8x = 8*(-2) = -16

Therefore, the value of 8x is -16.
What is the solution of the equation −8x = −0.56
?
To solve the equation -8x = -0.56, we need to isolate x.

Dividing both sides of the equation by -8 gives:
x = (-0.56)/(-8)

Simplifying the right side of the equation, we have:
x = 0.07

Therefore, the solution to the equation -8x = -0.56 is x = 0.07.
What is the solution of the equation 4/3x=−6/5
?(1 point)
To solve the equation (4/3)x = (-6/5), we need to isolate x.

Multiplying both sides of the equation by (3/4) gives:
(3/4)(4/3)x = (3/4)(-6/5)
x = (-18/20)

Simplifying the right side of the equation, we have:
x = (-9/10)

Therefore, the solution to the equation (4/3)x = (-6/5) is x = (-9/10).

To solve the equation (5/2)x = (-1/8), we need to isolate x.

Multiply both sides of the equation by (2/5):
(2/5)(5/2)x = (2/5)(-1/8)
x = (-2/40)

Simplifying the right side of the equation, we have:
x = (-1/20)

Therefore, the solution to the equation (5/2)x = (-1/8) is x = (-1/20).

The answer is d) Start Fraction 1 over 20 End Fraction.

To solve the equation -x/2.9 = -3, we can start by multiplying both sides of the equation by 2.9 to eliminate the fraction:

2.9 * (-x/2.9) = 2.9 * (-3)

After simplifying, we have:

-x = -8.7

To solve for x, we can multiply both sides by -1 to isolate x:

(-1)(-x) = (-1)(-8.7)

x = 8.7

Therefore, the solution to the equation -x/2.9 = -3 is x = 8.7.

The answer is c) 8.7.

To solve the equation (8/5)x = -10, we need to isolate x.

Multiply both sides of the equation by (5/8):
(5/8)(8/5)x = (5/8)(-10)
x = (-50/8)

Simplifying the right side of the equation, we have:
x = (-25/4)

Therefore, the solution to the equation (8/5)x = -10 is x = (-25/4).

The answer is c) negative Start Fraction 25 over 4 End Fraction.
