What do you do first 3x + -4 = -19

Step-by-step explanation:

3x + -4 = -19

3x -4 = -19

3x = -19 + 4

3x = -15

x = -5

Step-by-step explanation:

3x -4 = -19

3x = -19+4

3x = -15

x = -15/3

x = -5

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
