Question

If x/3 + 27 = 30, what is the value of x? a. 3 b. 6 c. 9 d. 12 e. 27

Answer 1

Hello!

Answer:

`\Large \boxed{\sf x = 9}`

Explanation:

We want to solve the following equation:

`\sf (x)/(3) + 27 = 30`

It's a first degree equation, we will isolate x.

▪ First, subtract 27 from both sides:

`\sf (x)/(3) + 27 -27= 30-27`

Simplify:

`\sf (x)/(3) = 3`

▪ Finally, multiply both sides by 3:

`\sf (x)/(3) * 3 = 3 * 3`

Simplify:

`\boxed{\sf x = 9}`

Conclusion:

The value of x is 9.
