Write an equation and solve for the unknown number.Twice a number, increased by 3 is 7.(1 point)

Answer 1

Let x represent the unknown number.

The equation can be written as:

2x + 3 = 7

To solve for x, we can subtract 3 from both sides of the equation:

2x + 3 - 3 = 7 - 3

This simplifies to:

2x = 4

Finally, we can divide both sides of the equation by 2:

2x/2 = 4/2

This simplifies to:

x = 2

Therefore, the unknown number is 2.
