Solve for x: 3x + 5 = 14

• x = 6

• x = 5

• x = 3

• x = 4

Answer explanation

Subtract 5 from both sides to isolate 3x, then divide by 3 to find x = 3.

Find the value of x in the equation: 2x - 7 = 11

• 5

• 13

• 3

• 9

Answer explanation

To find x, add 7 to both sides of the equation: 2x = 18. Then, divide by 2 to get x = 9. Therefore, the correct answer is 9.

What is the solution to the equation: 4x = 20

• x = 2

• x = 10

• x = 5

• x = 4

Answer explanation

To solve the equation 4x = 20, divide both sides by 4 to isolate x. Therefore, x = 20 / 4 = 5. Hence, the correct answer is x = 5.

Determine the value of x in the equation: 5x - 3 = 22

• x = 5

• x = 3

• x = 10

• x = 7

Answer explanation

To solve for x, add 3 to both sides of the equation: 5x = 25. Then divide by 5 to get x = 5. Therefore, x = 5 is the correct choice.

Solve for x: 6x + 9 = 33

• x = 5

• x = 7

• x = 4

• x = 6

Answer explanation

To solve for x, first subtract 9 from both sides to isolate 6x. This gives 6x = 24. Then, divide by 6 to find x = 4. Therefore, x = 4 is the correct choice.

Find the value of x in the equation: 3x - 4 = 8

• x = 4

• x = 5

• x = 2

• x = 10

Answer explanation

To find the value of x, add 4 to both sides of the equation: 3x - 4 + 4 = 8 + 4. Simplify to get 3x = 12. Divide by 3 to get x = 4. Therefore, x = 4 is the correct choice.

What is the solution to the equation: 2x = 16

• x = 4

• x = 12

• x = 10

• x = 8

Answer explanation

To solve the equation 2x = 16, divide both sides by 2 to isolate x. Therefore, x = 16 / 2 = 8. Hence, the correct answer is x = 8.

Determine the value of x in the equation: 4x - 7 = 25

• x = 12

• x = 15

• x = 10

• x = 8

Answer explanation

To solve for x, add 7 to both sides of the equation: 4x = 32. Then, divide by 4 to find x = 8. Therefore, the correct answer is x = 8.

Solve for x: 7x + 8 = 43

• x = 5

• x = 7

• x = 6

• x = 10

Answer explanation

To solve for x, first subtract 8 from both sides: 7x = 35. Then divide by 7 to find x = 5. Therefore, the correct answer is x = 5.

Find the value of x in the equation: 5x - 6 = 24

• x = 10

• x = 8

• x = 6

• x = 12

Answer explanation

To find the value of x, add 6 to both sides of the equation: 5x = 30. Then, divide by 5 to get x = 6. Therefore, x = 6 is the correct choice.
