Answer:

1 We set z=-4

(2*-4 + b)(-4 - 3) = 0

(-8 + b)(-7) = 0

Set the factor (-8 + b) equal to 0.

-8 + b = 0

Solving for b, we get 8

b = 8

2We simplify the equation to the form, which is simple to understand  

6x-12=51-3x

We move all terms containing x to the left and all other terms to the right.  

+6x+3x=+51+12

We simplify left and right side of the equation.  

+9x=+63

We divide both sides of the equation by 9 to get x.  

x=7

3 Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 6x = 35 + -8

Combine like terms: 8 + -8 = 0

0 + 6x = 35 + -8

6x = 35 + -8

Combine like terms: 35 + -8 = 27

6x = 27

Divide each side by '6'.

x = 4.5

Simplifying

x = 4.5

4 Combine like terms: 6x + x = 7x

14 + 7x = 70

Solving

14 + 7x = 70

Solving for variable 'x'.

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

Add '-14' to each side of the equation.

14 + -14 + 7x = 70 + -14

Combine like terms: 14 + -14 = 0

0 + 7x = 70 + -14

7x = 70 + -14

Combine like terms: 70 + -14 = 56

7x = 56

Divide each side by '7'.

x = 8

Simplifying

x = 8

5 15-4=11+3=14

19-14= x=5

6Combine like terms: -2 + 10 = 8

8 + 6x + 8x = 8

Combine like terms: 6x + 8x = 14x

8 + 14x = 8

Add '-8' to each side of the equation.

8 + -8 + 14x = 8 + -8

Combine like terms: 8 + -8 = 0

0 + 14x = 8 + -8

14x = 8 + -8

Combine like terms: 8 + -8 = 0

14x = 0

Solving

14x = 0

Solving for variable 'x'.

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

Divide each side by '14'.

x = 0

Simplifying

x = 0

7idk sorry

8Solving

0.8 + 0.4x = 2

Solving for variable 'x'.

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

Add '-0.8' to each side of the equation.

0.8 + -0.8 + 0.4x = 2 + -0.8

Combine like terms: 0.8 + -0.8 = 0.0

0.0 + 0.4x = 2 + -0.8

0.4x = 2 + -0.8

Combine like terms: 2 + -0.8 = 1.2

0.4x = 1.2

Divide each side by '0.4'.

x = 3

Simplifying

x = 3

Step-by-step explanation:

i hope this is right good luck
