Question

If m = 19 what is b? m = 3b + 4

Answer 1

Answer: b=5

Explanation:

19=3b+4

19-4=3b

15=3b

5=b

Answer 2

Answer: b = 5

Given that m = 19, we must plug 19 in for m in the given equation:

19 = 3b + 4

From here, we can use simple algebra to solve for b.

Subtract 4 from both sides on the equation:

15 = 3b

Now simply divide both sides by 3:

5 = b
