17 = -13 -8x

Add 13 to both sides:

30 = -8x

Divide both sides by -8:

x = 30 / -8

Reduce the fraction by dividing both numbers by 2:

X = -15/4 or - 3 3/4

6 = x +2/3

Subtract 2/3 from both sides:

x = 5 1/3

13 + w/7 = -18

Subtract 13 from both sides:

w/7 = -31

Multiply both sides by 7:

w = -217

Answer:

1) x = -3.75

2) x = 5.33

3) w = -217

Step-by-step explanation:

1) 17 = -13 -8x

Rearranging the terms of the equation:

=> 8x = -13-17

=> 8x = -30

Computing the value of x:

=> x = -30/8 = -15/4 = -3.75

So the required value of x is -3.75

2) 6 = x +2/3

Rearranging the terms of the equation:

=> x = 6-2/3

    x = (18-2)/3

Simplifying:

    x = 16/3 = 5.33

So the required value of x is 5.33

3) 13 + w/7 = -18

Rearranging the terms of the equation:

=> w/7 = -18-13 = -31

Computing the value of w:

=> w = -31 * 7 = -217

So the required value of w is -217

Graph the system of inequalities to show all possible solutions.<br> {y&lt;3x-2<br> {y ≥ -x+3
Semmy [17]

Answer:

see attachment for graph

Step-by-step explanation:

< or > : dashed line

≤ or ≥ : solid line

< or ≤ : shade below the line

> or ≥ : shade above the line

<u>To graph the line y < 3x-2</u>

Rewrite the equation as: y = 3x - 2

Find two points on the line:

when x = 0,  y = 3(0) - 2 = -2  →  (0, -2)

when x = 3,  y = 3(3) - 2 = 7  →  (3, 7)

Plots the found points (0, -2) and (3, 7).

Draw a straight, dashed line through the points.

<u>To graph the line y ≥ -x + 3</u>

Rewrite the equation as: y = -x + 3

Find two points on the line:

when x = 0,  y = -(0) + 3 = 3  →  (0, 3)

when x = 3,  y = -(3) + 3 = 0  →  (3, 0)

Plots the found points (0, 3) and (3, 0).

Draw a straight, solid line through the points.

Shade above the solid line and below the dashed line to the right of where the two lines intersect.  <u>The shaded area is the area of all possible solutions</u>.
