Question

The sum of 4 and 7x is equal to 25.

Answer 1

x = 3 (7+4x=25 for only equation)

Explanation:

"The sum of 4 and 7x" is equivalent to 4 + 7x mathematically. "Is equal to 25" is equivalent to = 25. Therefore, by adding both together, we have:

`\displaystyle{4+7x=25}`

Subtract both sides by 4:

`\displaystyle{4+7x-4=25-4}\\\\\displaystyle{7x=21}`

Divide both sides by 7:

`\displaystyle{(7x)/(7)=(21)/(7)}\\\\\displaystyle{x=3}`

Therefore, x = 3

If you only want the equation, you can answer only "4+7x=25"
