Inverse operations

Front

Simplify the equation: 5x + 6 = 2 + 3x. Does it have one, no, or infinite solutions?

Back

One solution

Front

Solve for x: 8x - 10 = -34.

Back

x = -3

Front

Which equation has a = 5 as the solution? a + 15 = 10, 2a = 5, 2a = 10, a - 15 = 10

Back

2a = 10

Front

Solve: 3x + 9 = 0.

Back

x = -3

Front

What is the first step to solve the equation: 2x + 4 = 12?

Back

Subtract 4 from both sides.

Front

If an equation has no solutions, what does that mean?

Back

The lines representing the equations are parallel.

Front

What is the solution to the equation: 4x - 8 = 0?

Back

x = 2

Front

What does it mean if an equation has infinite solutions?

Back

The equations represent the same line.

Front

Solve for x: 5(x - 2) = 15.

Back
