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

Mathematics
1 answer:
Olegator [25]2 years ago
6 0

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

I do t o wish she sksnheisnmakakabs nsjd
dusya [7]

Answer:

x=-12

Step-by-step explanation:

(-22 + 3x) /( 3x+7) =2

Multiply each side of the equation by 3x+7

-22+3x = 2(3x+7)

Then distribute

-22 +3x = 6x+14

Subtract 3x from each side

-22 = 3x+14

Subtract 14 from each side

-36 = 3x

Divide by 3

-12 =x
