Two Step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

Solve for x: 4x + 7 = 23

Back

x = 4

Front

Solve for n: 2n + 10 = -2

Back

n = -6

Front

Solve for y: -15 = -4y + 5

Back

y = 5

Front

Solve for z: 6z + 3 - 4z = 9

Back

z = 3

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front

What is the first step to solve the equation 4x + 7 = 23?

Back

Subtract 7 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation 2n + 10 = -2?

Back

Subtract 10 from both sides, then divide by 2.

Front

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

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

What is the purpose of balancing an equation?

Back

Balancing an equation ensures that both sides remain equal after performing operations.
