Self - Assessment: One Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step by performing the same operation on both sides of the equation.

Front

Solve: -9 = 28 + y

Back

y = -37

Front

What is the first step to solve the equation y + 4.6 = 12?

Back

Subtract 4.6 from both sides of the equation.

Front

Solve for y: y + 4.6 = 12

Back

y = 7.4

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 opposite side.

Front

Solve: -2s = -38

Back

s = 19

Front

What operation would you use to solve the equation r - 6 = -9?

Back

Add 6 to both sides of the equation.

Front

Solve the equation: r - 6 = -9

Back

r = -3

Front

What is the purpose of checking your solution in an equation?

Back

To verify that the solution satisfies the original equation.
