Solve for b.
46 + 5 = 1 + 5b

b = 10

Step-by-step explanation:

Solve for b:

46 + 5 = 5 b + 1

46 + 5 = 51:

51 = 5 b + 1

51 = 5 b + 1 is equivalent to 5 b + 1 = 51:

5 b + 1 = 51

Subtract 1 from both sides:

5 b + (1 - 1) = 51 - 1

1 - 1 = 0:

5 b = 51 - 1

51 - 1 = 50:

5 b = 50

Divide both sides of 5 b = 50 by 5:

(5 b)/5 = 50/5

5/5 = 1:

b = 50/5

The gcd of 50 and 5 is 5, so 50/5 = (5×10)/(5×1) = 5/5×10 = 10:

b = 10
