1. Combine like terms: In the given equation, combine 3n and 4n, which gives 7n. So the equation becomes 7n + 9 = 2.

2. Subtract 9 from both sides: To isolate the variable n, subtract 9 from both sides of the equation. This gives 7n = -7.

3. Divide both sides by 7: To solve for n, divide both sides of the equation by 7. This gives n = -1.

An expression for the base of the triangle: Let the height of the triangle be h cm. According to the given information, the base is 4 less than three times the height. So, the expression for the base can be written as 3h - 4 cm.

Equation for the area of the triangle: The area of a triangle can be calculated using the formula A = (base × height) / 2. In this case, the area is given as 38 square cm. So, the equation for the area of the triangle is 38 = (3h - 4 × h) / 2.

The first step in solving for h: To solve for the height, we need to simplify the equation for the area of the triangle. This may involve distributing, combining like terms, or isolating variables.
