Question

If 5x + 60 = 75, what is the value of x? a. 3 b. 4 c. 5 d. 6 e. 7

Answer 1

Answer: a, 3

Step-by-step explanation: 5x + 60 = 75 <=> 5x + 60 - 60 = 75 - 60 <=> 5x = 15 <=> x = 3

Answer 2

Hello!

Answer:

`\Large \boxed{\sf x = 3}`

Explanation:

We want to solve the following equation:

`\sf 5x + 60 = 75`

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

▪ First, subtract 60 from both sides:

`\sf 5x + 60-60 = 75-60`

Simplify:

`\sf 5x = 15`

▪ Finally, divide both sides by 5:

`\sf (5x)/(5) = (15)/(5)`

Simplify:

`\boxed{\sf x = 3}`

Conclusion:

The value of x is 3.
