Answer:

x = -19

Step-by-step explanation:

First, we solve for x. Distribute first.

$-4(x+1)-3=-3(x-4)\\$

$-4x-4 -3=-3x+12$ .

Then, Combine Like Terms.

$-4x-7=-3x+12$

Then, Add 3x to both sides, and add 7 to both sides.

$-x=19$

Finally, divide both sides by -1.

$x=-19$

The pair of values below is from a direct variation. Find the missing number.

NISA [10]

Answer:

The answer is 2.

2 since 6/4=3/2

Step-by-step explanation:

Since your relation is a direct variation then the points on your line are of the form y=kx where k is the constant of variation (also called constant of proportionality)

If y=kx then y/x=k.

So all the points in this relation since it is a direct variation will be equal to y-coordinate/x-coordinate.

So we are going to solve this proportion:

$\frac{6}{4}=\farc{3}{x}$

Again I put y/x from each point. They should have same ratio because this is a direct variation.

Cross multiply:

$6(x)=4(3)$

$6x=12$

Divide boht sides by 6:

$x=\frac{12}{6}$

$x=2$
