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.
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.
