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

Back

To isolate a variable, perform the inverse operations in reverse order. First, eliminate the constant term by adding or subtracting, then divide or multiply to solve for the variable.

Front

Solve the equation: 0.4x + 13 = 3

Back

x = -25

Front

What is the first step to solve the equation: -1.5x - 14 = -20?

Back

Add 14 to both sides of the equation to eliminate the constant term.

Solve the equation: -1.5x - 14 = -20

Back

x = 4

Front

What does it mean to 'balance' an equation?

Back

Balancing an equation means ensuring that both sides of the equation are equal by performing the same operation on both sides.
