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

Back

To isolate a variable, perform inverse operations in the reverse order of operations. First, eliminate any constant added or subtracted from the variable, then divide or multiply to solve for the variable.

Front

Solve for y: 4y + 1 = 13

Back

y = 3

Front

Solve for a: 6 - 3a = 21

Back

a = -5

Front

Back

Multiply both sides by 3 to eliminate the fraction.

Back

x = 10

Front

What does it mean to check your solution in an equation?

Back

Checking your solution means substituting the value back into the original equation to verify that both sides are equal.

Front

Solve for x: 2x + 5 = 15

Back

x = 5

Front

What is the solution to the equation 3x - 9 = 0?

Back

x = 3

Front

How do you solve the equation 5x + 2 = 17?

Back

Subtract 2 from both sides to get 5x = 15, then divide by 5 to find x = 3.
