Back

y = -2

Front

What is the first step to solve the equation 90h + 60 = 600?

Back

Subtract 60 from both sides to isolate the term with the variable.

Front

Solve: 3c + 5 = 23

Back

c = 6

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the other side.

Front

Solve: 2x - 7 = -23

Back

x = -8

Front

What is the purpose of using equations in real-life scenarios?

Back

Equations help to model and solve problems involving relationships between quantities.

Front

Back

n = -5

Front

What is the general form of a two-step equation?

Back

The general form is ax + b = c, where a, b, and c are constants.

Front

How do you check if your solution to an equation is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.
