Answer:

x = -7

Step-by-step explanation:

Use the distibutive property on both side:

Right side:

4 ( 1 - x )

( 4 x 1 ) + 4 x -X )

4 - 4x

Left side:

-3 ( x + 1 )

( -3 x X ) + ( -3 x 1 )

-3x -3

4 - 4x + 2x = -3x - 3

Combine like terms:

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

-2x + 4 = -3x - 3

Add 3 to each side:

-2x + 7 = -3x

add 2x to each side:

7 = -x

Divide each side by -1:

-7 = x

Answer:

B 3x-2y=10

Step-by-step explanation:

This is correct because when solved it has the same slope as line <em>k.</em>

The slope of <em>k</em> is 3/2.

3x-2y=10

first subtract 3x from both sides

-2y=-3x+10

next divide both sides by -2

y=3/2x-5

this shows that the slope 3/2 is the same as line <em>k</em>

I know it may be too late, but maybe it will eventually help you or someone else.

If a plane travels with a speed of 570 miles per hour for 7 hours, then he will travel 570 * 7 = 3990 miles in that time.
