Question

6) Solve for x. 2/3 (x + 7) = 10

A)22

B)8

C)- 1 /3

D)41/ 3

Answer 1

For this case we must find the value of the variable "x" of the following equation:

`\frac {2} {3} (x + 7) = 10`

We multiply by 3 on both sides of the equation:

`2 (x + 7) = 30`

We divide between 2 on both sides of the equation:

`(x + 7) = 15\\x + 7 = 15`

We subtract 7 on both sides of the equation:

`x = 8`

Answer:

Option B
