−15x=120 (9 points)x=

To solve for x, we need to isolate x on one side of the equation.

Starting with the equation -15x = 120, let's divide both sides by -15:

(-15x)/(-15) = 120/(-15)

This simplifies to:

x = -8

Therefore, x is equal to -8.

x−25=19 (9 points)x=

To solve for x, we need to isolate x on one side of the equation.

Starting with the equation x - 25 = 19, let's add 25 to both sides:

(x - 25) + 25 = 19 + 25

This simplifies to:

x = 44

Therefore, x is equal to 44.

−3x+2=14 (9 points)x=

To solve for x, we need to isolate x on one side of the equation.

Starting with the equation -3x + 2 = 14, let's subtract 2 from both sides:

(-3x + 2) - 2 = 14 - 2

This simplifies to:

-3x = 12

Next, we divide both sides by -3:

(-3x) / -3 = 12 / -3

This gives us:

x = -4

Therefore, x is equal to -4.

−2y−8=15 (9 points)y=

To solve for y, we need to isolate y on one side of the equation.

Starting with the equation -2y - 8 = 15, let's add 8 to both sides:

(-2y - 8) + 8 = 15 + 8

This simplifies to:

-2y = 23

Next, we divide both sides by -2:

(-2y) / -2 = 23 / -2

This gives us:

y = -23/2

Therefore, y is equal to -23/2 or -11.5.

5(x−2)=21x=

To solve for x, we need to isolate x on one side of the equation.

Starting with the equation 5(x - 2) = 21, let's simplify the left side first by distributing the 5:

5x - 10 = 21

Next, let's isolate x by adding 10 to both sides:

5x - 10 + 10 = 21 + 10

This simplifies to:

5x = 31

Finally, divide both sides by 5 to solve for x:

(5x) / 5 = 31 / 5

This gives us:

x = 31/5

Therefore, x is equal to 31/5 or 6.2.

x+19+7x+1=−200x=

To solve for x, we need to simplify the equation and then isolate x.

Starting with the equation x + 19 + 7x + 1 = -200, let's combine like terms:

8x + 20 = -200

Next, let's isolate x by subtracting 20 from both sides:

8x + 20 - 20 = -200 - 20

This simplifies to:

8x = -220

To solve for x, divide both sides by 8:

(8x) / 8 = -220 / 8

This gives us:

x = -27.5

Therefore, x is equal to -27.5.
