Answer:

b = $\frac{7}{12}$

Step-by-step explanation:

b + $\frac{2}{3}$ = 1 $\frac{1}{4}$ ← change to an improper fraction

b + $\frac{2}{3}$ = $\frac{5}{4}$

Multiply through by 12 ( the LCM of 3 and 4 ) to clear the fractions

12b + 8 = 15 ( subtract 8 from both sides )

12b = 7 ( divide both sides by 12 )

b = $\frac{7}{12}$

The line passing through (1,4) and (-4,-1) has the following slope:

-1 - 4 -5
m = ------------ = -------- = +1
-4 - 1 -5

Find the slope of the line passing thru the other set of points. Graph both lines. What do you see? Do the 2 lines have any particular relationship to one another?

I solved this by hand first, then cymath, then Wolfram alpha. we all agree the solution to the equation involved is x=-3 however -3 is not a multiple of 6. if you plug it in you get a solution of 24 but I don't consider this to be a valid question.
