What's the answer to this question 3x + 2y = -4 and how did you get it

1 answer:

6 0

First you subtract 3x because you are trying to get x alone so subtract 3x on both side so you would get 2y=-3x-4 and then divide the whole thing by 2 so you would get y=-3-4/2 and then you simplify and get y=-7/2 so y=-7/2 is your answer.

Solve for x. 3x−1=9x+2 Enter your answer in the box. x =

julia-pushkina [17]

Answer:

x= -1

Step-by-step explanation:

3x-1=2x2 (calculate the product)

3x-1=4x (move terms)

3 x - 4 x =1 (collect the terms)

- x = 1 (change the signs)

Solution is x = -1

Solve the system of linear equations using elimination.

N76 [4]

Answer:

C (-2,1)

Step-by-step explanation:

−2x − y = 3 (1)

−9x − y = 17 (2)

(1) y = -2x - 3

(2) y = -9x - 17

-2x - 3 = -9x - 17

7x = -14

x = -2

y = -2(-2) - 3

y = 4 - 3

y = 1

For each of the solutions of the equations find two consecutive integers between which the solution is located.

adoni [48]

Using squares of integers numbers, it is found that the solution of the equation is located between the integers x = 1 and x = 2.

The equation given is:

$x^2 = 3$

The solution of the equation given is:

$x = \sqrt{3}$

The squares of the integers numbers until the square root of 3 are:

$1^2 = 1$

$2^2 = 4$

Since $1 < 3 < 4$ , the square root of 3, which is the solution to the equation, is located between the integers x = 1 and x = 2.
