Solve for x. 2/3x−5=21 x = 39 x=52/3 x = 24 x=32/3

2x/3 - 5 = 21

2x/3 = 26

2x = 78

x = 39

OPTION A is the answer

The value of x obtained on solving the equation is:

                             x=39

We are given a equation in terms of the variable x as follows:

Now on adding 5 on both the sides of the equation we have:

On multiplying both side by 3/2 we get:

                 Hence, the answer is:   x = 39

answer: -1

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
