Question

Type the correct answer in each box. Use numerals instead of words. If Necessary, use / for the fraction bars. Consider the equation below.

-2(bx-5)=16

The Value of x in terms of b is ______
The Value of x when b is 3 is _______​

Answer 1

-3/b; -1

Explanation:

A. Solve the equation

`\begin{array}{rcr}-2(bx - 5) & = & 16\\bx - 5 & = & -8\\bx & = & -3\\x & = & \boxed{\mathbf{-3/b}}\\\end{array}`

B. Value when b = 3

`\begin{array}{rcr}x & = & -3/3\\x & = & \boxed{\textbf{-1}}\\\end{array}`

Answer 2

x = -3/b

x = -1

Explanation:

-2(bx-5)=16

Divide each side by -2

-2(bx-5)/-2=16/-2

bx-5 = -8

Add 5 to each side

bx-5+5 = -8+5

bx = -3

Divide each side by b

bx/b = -3/b

x = -3/b

If b = 3

x = -3/3

x = -1
