Practice on Solve one Step equations (Addition)

What is a one-step equation?

• An equation that can be solved in a single step, typically involving addition or subtraction.

• An equation that requires multiple steps to solve.

• An equation that has no solution.

• An equation that involves multiplication or division only.

How do you solve the equation r + 20 = 27?

• Subtract 20 from both sides: r = 27 - 20, so r = 7.

• Add 20 to both sides: r = 27 + 20, so r = 47.

• Multiply both sides by 20: r = 27 * 20, so r = 540.

• Divide both sides by 20: r = 27 / 20, so r = 1.35.

How do you solve the equation 15 = 4 + x?

• x = 15 - 4, so x = 11

• x = 15 + 4, so x = 19

• x = 4 - 15, so x = -11

• x = 4 + 15, so x = 11

What is the solution to the equation a + 2 = 16?

• a = 12

• a = 14

• a = 16

• a = 10

What does it mean if an equation has no solution?

• It means there is no value for the variable that makes the equation true.

• It means the equation has infinite solutions.

• It means the equation is always true for any value of the variable.

• It means the equation has at least one solution.

What is the value of v in the equation v + 23 = 45?

• 20

• 22

• 25

• 18

How do you check your solution for the equation z + 4 = 12?

• Substitute z back into the original equation: 8 + 4 = 12, which is true.

• Multiply both sides of the equation by 2.

• Add 4 to both sides of the equation and solve for z.

• Subtract 4 from both sides of the equation and check if z = 8.

What is the solution to the equation m + 15 = 30?

• m = 10

• m = 12

• m = 15

• m = 20

What is the first step in solving the equation x + 5 = 12?

• Add 5 to both sides to isolate x.

• Subtract 5 from both sides to isolate x.

• Multiply both sides by 5 to isolate x.

• Divide both sides by 5 to isolate x.

What is the inverse operation of addition?

• Multiplication

• Subtraction

• Division

• Exponentiation
