(Literal Equations) Solve each equation or formula for the variable indicated 2/3y + v = x, for y

y = 3/2( x-v)

Step-by-step explanation:

2/3y + v = x

Subtract v from each side

2/3y + v-v = x-v

2/3y = x-v

Multiply each side by 3/2

3/2 *2/3y  =3/2( x-v)

y = 3/2( x-v)

answer are

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
