Make an equation for this problem:
2(7 + x) + 3 = 25
Twice the sum of 7 and a number: 2(7 + x)
Three more than: + 3
is 25: = 25
---
Solve the equation by distributing 2 inside the parentheses.
14 + 2x + 3 = 25
Combine like terms.
17 + 2x = 25
Subtract 17 from both sides.
2x = 8
Divide both sides by 2.
x = 4
The number is 4.
