1. -3x + 23 = 2x + 8
x=

x = 3

Step-by-step explanation:

Subtract  23  from both sides of the equation

Simplify

Subtract  2x from both sides of the equation

Simplify

Divide both sides of the equation by the same term

Simplify

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

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
