7+3/5b=7/10b what is b

Olegator [25]

Answer:

b = 70

Step-by-step explanation:

7+3/5b=7/10b

Subtract 3/5 b from each side

7+3/5b - 3/5 b=7/10b - 3/5 b

7 = 7/10 b - 3/5 b

We need to get a common denominator or 10 on the right hand side

7 = 7/10 b -3/5 *2/2 b

7 = 7/10b - 6/10 b

7 = 1/10 b

Multiply each side by 10

7*10 = 1/10 * 10 b

70 = b
