• 3/5

• 4/5

• 1/5

• 2/5

What is the result of cross-multiplying in the equation x/(-18.1) = -9.4?

• x = -9.4 * 18.1

• x = 9.4 * 18.1

• x = 9.4 / 18.1

• x = -9.4 / 18.1

What is the value of x in the equation x/(-18.1) = -9.4 after solving?

• 171

• -170.14

• 170.14

• -171

How do you rewrite the equation x - (-42) = -51 to simplify it?

• x + 42 = -51

• x - 42 = -51

• x + 42 = 51

• x - 42 = 51

What is the solution to the equation x + 42 = -51?

• -9

• -93

• 93

• 9

What is the first step in solving the equation x - (-42) = -51?

• Rewrite as x - 42 = 51

• Rewrite as x + 42 = -51

• Rewrite as x - 42 = -51

• Rewrite as x + 42 = 51
