Step 1: Response area to get Response area
Step 2: Response area to get Response area
Step 3: Response area to get
Step 1: Combine like terms.
The simplified equation becomes 7n + 9 = 2.
Step 2: Subtract 9 from both sides of the equation.
The simplified equation becomes 7n = -7.
Step 3: Divide both sides of the equation by 7.
The simplified equation becomes n = -1.

An expression for the base of the triangle:. Response area
Equation for the area of the triangle: Response area
The first step in solving for h:
An expression for the base of the triangle: 3h - 4
Equation for the area of the triangle: A = (3h - 4) × h / 2
The first step in solving for h: Set the equation for the area equal to 38: (3h - 4) × h / 2 = 38

2(x−5)+2x=10
2 times open paren x minus 5 close paren plus 2 x is equal to 10
2x+12=−3x−27
2 x plus 12 is equal to negative 3 x minus 27
4x−17+2x=9
4 x minus 17 plus 2 x is equal to 9
2x+12=27
2x+12=27
