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

How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform the inverse operations in reverse order: first undo addition or subtraction, then undo multiplication or division.

Front

Solve for a in the equation: 15 = 2a + 7

Back

a = 4

Front

Solve for x in the equation: 9 + 3x = 10

Back

x = 1/3

Front

What is the first step to solve the equation 4p + 5 = 17?

Back

Subtract 5 from both sides to get 4p = 12.

Front

Solve for p in the equation: 4p + 5 = 17

Back

p = 3

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means keeping both sides equal by performing the same operation on both sides.

Front

Solve for x in the equation: x/3 + 10 = 15

Back

x = 15.

Front

What is the second step to solve the equation 3c + 5 = 23?

Back

Subtract 5 from both sides to get 3c = 18.

Front

Solve for c in the equation: 3c + 5 = 23

Back

c = 6
