Answer:

x= -12

Step-by-step explanation:

move variable to left and change its sign

= 4x - 20 = -68

move constant to the right and change its sign

= 4x = -68 + 20

calucate the sum

= 4x = -48

divide both sides of the equation by 4

x= -12

Solve these equations. 1. -16 = v - 14 2. -2n = -22 3. 25 = b + 7

leonid [27]

1) -16 = v - 14

Add 14 to both sides.

v = -2

2) -2n = -22

Divide both sides by -2.

n = 11

3) 25 = b + 7

Subtract 7 from both sides.

b = 18

How do you solve 6-9(4p-3)= 2(6p+7)+3

Alika [10]

Answer:

p= 1/3

=0.333

Step-by-step explanation:

Simplifying

6 + -9(4p + -3) = 2(6p + 7) + 3

Reorder the terms:

6 + -9(-3 + 4p) = 2(6p + 7) + 3

6 + (-3 * -9 + 4p * -9) = 2(6p + 7) + 3

6 + (27 + -36p) = 2(6p + 7) + 3

Combine like terms: 6 + 27 = 33

33 + -36p = 2(6p + 7) + 3

Reorder the terms:

33 + -36p = 2(7 + 6p) + 3

33 + -36p = (7 * 2 + 6p * 2) + 3

33 + -36p = (14 + 12p) + 3

Reorder the terms:

33 + -36p = 14 + 3 + 12p

Combine like terms: 14 + 3 = 17

33 + -36p = 17 + 12p

Solving

33 + -36p = 17 + 12p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-12p' to each side of the equation.

33 + -36p + -12p = 17 + 12p + -12p

Combine like terms: -36p + -12p = -48p

33 + -48p = 17 + 12p + -12p

Combine like terms: 12p + -12p = 0

33 + -48p = 17 + 0

33 + -48p = 17

Add '-33' to each side of the equation.

33 + -33 + -48p = 17 + -33

Combine like terms: 33 + -33 = 0

0 + -48p = 17 + -33

-48p = 17 + -33

Combine like terms: 17 + -33 = -16

-48p = -16

Divide each side by '-48'.

p = 0.3333333333

Simplifying

p = 0.3333333333

Graph the solution set to the system Y<15-0.41

Vlad [161]

Answer:

The graph in the attached figure

Step-by-step explanation:

The correct question is

Graph the solution set to the system

Y<(1/5)x-0.41

we have

$y$

The solution is the shaded area below the dashed line $y=\frac{1}{5}x-0.41$

The slope of the dashed line is positive $m=\frac{1}{5}$

The y-intercept of the dashed line is (0,-0.41)

The x-intercept of the dashed line is (2.05,0)

To find out the solution set, draw the intercepts and connect them to plot the dashed line, and shade the area below the dashed line

If x-1/3 = kand k = 3, what is the value of x? a. 2 b. 4 c. 9 d. 10

frosja888 [35]

Answer:

X=10

Step-by-step explanation:

Plug 3 into the k in the first equation. Multiply by 3 to cancel out the fraction. This leaves you with x-1=9. Add 1 to both sides and you get x=10.
