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 8.
The number is 20.
The number is 5.
Let's call the unknown number "x". According to the given information, we can create the following equation:
2x + 3 = 7
Now, let's solve for x.
Subtracting 3 from both sides:
2x = 4
Dividing both sides by 2:
x = 2
So the unknown number is 2.
