Write an equation and solve to find the numbers and show work.
7. Twice the sum of a number and three is 88.
Let the number be x.
Twice the sum of a number and three: 2(x + 3)
According to the problem, it is equal to 88:
2(x + 3) = 88
Simplifying the equation:
2x + 6 = 88
Subtracting 6 from both sides:
2x = 82
Dividing both sides by 2:
x = 41
Therefore, the number is 41.
