Answer:

x=-4

Step-by-step explanation:

4(x+4)=0

multiply x and 4 by 4

4x+16=0

subtract 16 from both sides.

4x=-16

divide both sides by 4

x=-4

3 consecutive odd integers such that the sum of twice the first and three times the second is 55 more than twice the third
den301095 [7]

Answer:

Consecutive odd integers are 19 , 21 & 23

Step-by-step explanation:

Let the first 3 consecutive odd intergers be x , (x + 2) and (x + 4).

According to the question,

2x + 3(x + 2) = 2(x + 4) + 55

=  > 2x + 3x + 6 = 2x + 8 + 55

Eliminating 2x from both the sides,

=  > 3x + 6 = 63

=  > 3x = 63 - 6 = 57

=  > x =  \frac{57}{3}  = 19

So, the consecutive odd integers are = 19 , 21 & 23.

this week is a struggle for me i may have to have a tutor . but here is my problem 2x-3+3x= -28 what is th value of x?
pantera1 [17]

Answer:

x = -5

Step-by-step explanation:

2x-3+3x= -28

combine like terms

5x -3 = -28

add 3 to each side

5x-3+3 = -28+3

5x = -25

divide each side by 5

5x/5 = -25/5

x = -5

4(x+6)≤−56 it says Solve the inequality.
vlabodo [156]

\tt \: 4(x + 6) \leqslant  - 56

Divide both sides of the inequality by 4

\sf \: x + 6 \leqslant  - 14

Move the constant to the right-hand side and change its sign

\bf \: x \leqslant  - 14 - 6

Calculate the difference

\rm \: x \leqslant  - 20

And we are done solving!!~

Shalnov [3]

move variable to the left side and change its sign

-3x+8=6y

Move constant to the right side and change its sign

-3x=6y-8

Divide both sides of the equation by -3

x=-2y+8/3
