Question

Seven times a number is equal to 10 more than twice the number. use x as the variable

Answer 1

x=2

Explanation:

7x=10+2x

7x-2x=10

5x=10

x=2

Answer 2

`\sf x = 2`

Explanation:

Let's set up an equation to represent the given statement:

"Seven times a number is equal to 10 more than twice the number."

Let
`\sf x` be the variable representing the number. The equation is:

`\sf 7x = 2x + 10`

Now, let's solve for
`\sf x`:

Subtract
`\sf 2x` from both sides:

`\sf 7x - 2x = 10`

Combine like terms:

`\sf 5x = 10`

Divide both sides by 5:

`\sf x =(10)/(5)`

`\sf x = 2`

So, the solution to the equation is
`\sf x = 2`.
