Let's call the unknown number "x".
The equation to represent "Twice a number, increased by 3 is 7" would be:
2x + 3 = 7
To solve for the unknown number, we will isolate x:
2x + 3 - 3 = 7 - 3
2x = 4
Now, we divide both sides of the equation by 2 to solve for x:
2x/2 = 4/2
x = 2
Therefore, the unknown number is 2.
Write an equation and solve for the unknown number. Twice a number, increased by 3 is 7. (1 point)
