Write an equation and solve for the unknown number. Twice a number, increased by 3 is 7. (1 point) Responses The number is 2. The number is 2. The number is 8. The number is 8. The number is 20. The number is 20. The number is 5.

Answer 1

Let's represent the unknown number as "x".

The given condition states that "Twice the number, increased by 3, is 7."

Mathematically, we can write this as:

2x + 3 = 7

To solve for x, we need to isolate it on one side of the equation.

Subtracting 3 from both sides gives us:

2x = 7 - 3
2x = 4

Next, we divide both sides by 2 to solve for x:

x = 4/2
x = 2

Therefore, the unknown number is 2.
