One step and Two Step Equations Review

Front

What are coefficients in an expression?

Back

Coefficients are the numerical factors in terms of an algebraic expression. For example, in the expression 7x^2 + 5x - 3, the coefficients are 7 and 5.

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step, typically by adding, subtracting, multiplying, or dividing both sides by the same number.

Front

Solve for z: 12 + z = 15

Back

z = 3

Front

What is a two-step equation?

Back

A two-step equation requires two operations to isolate the variable. For example, in the equation 4x + 10 = -26, you first subtract 10 and then divide by 4.

Front

Solve for x: 4x + 10 = -26

Back

x = -9

Front

What does it mean to isolate a variable?

Back

Isolating a variable means to manipulate an equation so that the variable is on one side of the equation by itself.

Front

Solve for x: x - 8 = -5

Back

x = 3

Front

What is the first step to solve x/5 - 13 = 20?

Back

The first step is to add 13 to both sides of the equation.

Front

Solve for x: x/5 - 13 = 20

Back

x = 165

Front

What is the solution to an equation?

Back

The solution to an equation is the value of the variable that makes the equation true.
