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

Back

To isolate a variable, perform the inverse operations in the reverse order of operations.

Front

Solve for a: 33 = 4a - 7

Back

a = 10

Front

Solve for a: 20 = 2 - a

Back

a = -18

Front

Solve for c: 4c - 6 = 2

Back

c = 2

Front

Solve for a: -5 - 6a = -59

Back

a = 9

Front

Solve for d: 5d - 6 = 9

Back

d = 3

Front

What is the first step in solving the equation 4x + 5 = 17?

Back

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

Front

What is the second step in solving the equation 4x = 12?

Back

Divide both sides by 4 to get x = 3.

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means performing the same operation on both sides to maintain equality.
