Solutions

Chapter 1.5, Problem 8E

a.

To determine

Determine whether the value is a solution of the equation.

Expert Solution

Answer to Problem 8E

Yes, the given value is the solution of given equation.

Explanation of Solution

Given information:

  1[2(3x)]=4x(6+x)x=2

Formula used:

Putting value of x in equation.

  1[2(3x)]=4x(6+x)1[2(32)]=4(2)(6+2)1[21]=880=0

So, the given value is the solution of given equation.

b.

To determine

Determine whether the value is a solution of the equation.

Expert Solution

Answer to Problem 8E

No, the given value is not the solution of given equation.

Explanation of Solution

Given information:

  1[2(3x)]=4x(6+x)x=4

Formula used:

Putting value of x in equation.

  1[2(3x)]=4x(6+x)1[2(34)]=4(4)(6+4)1[2+1]=16101+1=6

  26

So, the given value is not the solution of given equation.
