Answer 3

To solve the equation 3x + 5 = 2x + 12, we need to isolate the variable x on one side of the equation. Follow these steps:

Step 1: Get all the x terms on one side of the equation and the constant terms on the other side.

Subtract 2x from both sides: (3x + 5) - 2x = (2x + 12) - 2x

Simplifying the equation: 3x - 2x + 5 = 12

Step 2: Combine like terms on the left side of the equation.

3x - 2x is x, so we have: x + 5 = 12

Step 3: Isolate the x term by moving the constant term (5) to the other side of the equation. To do this, we'll subtract 5 from both sides.

x + 5 - 5 = 12 - 5

Simplifying the equation: x = 7

So, the value of x that satisfies the equation is x = 7.
