Let's call the number "x".
The equation can be written as:
2x + 3 = 7
To solve the equation, we will isolate the variable "x".
Subtracting 3 from both sides:
2x = 7 - 3
2x = 4
Dividing both sides by 2:
x = 4/2
x = 2
Therefore, the solution to the equation is x = 2.
rite an equation and solve: Twice a number, increased by 3 is 7.
