Question

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). 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

The value of x in terms of b is x = $\frac{-3}{b}$. Therefore the value of x when b = 3 is x = $\frac{-3}{3}$ = -1.

We can find both answers by rearranging the equation to get "x =", and then substituting in 3 for b:

-2(bx - 5) = 16

-2bx + 10 = 16

- 10

-2bx = 6

÷ -2

bx = -3

÷ b

x = -3/b, which is the answer to the first part.

To get the second answer, we just substitute b = 3 into this equation and we get:

x = -3/b = -3/3 = -1

I hope this helps!
