If 2 inches on a scale drawing represents 9 feet in reality, how do you find the length on the drawing for an actual length of 36 feet?

Back

To find the length on the drawing, set up a proportion: (2 inches / 9 feet) = (x inches / 36 feet). Solving gives x = 8 inches.

What is the equation to find the value of n in n + (-7) = -77?

Back

To find n, add 7 to both sides: n = -77 + 7, which simplifies to n = -70.

Front

What is the value of n if n + 7 = 0?

Back

To find n, subtract 7 from both sides: n = 0 - 7, which simplifies to n = -7.

Front

What does it mean to solve an equation?
