Solve the equation: 5x + 2 = 17

• x = 3

• x = 4

• x = 5

• x = 6

Answer explanation

To solve the equation 5x + 2 = 17, we need to isolate the variable x. Subtracting 2 from both sides gives us 5x = 15. Dividing both sides by 5, we find that x = 3. Therefore, the correct choice is 'x = 3'. This answer explanation provides a step-by-step solution to the given question, highlighting the correct choice without mentioning the option number. It follows the specified conditions, ensuring that the explanation is within 75 words and is in English language.

Solve the equation: 2x + 37/7 = 5/7

• x = -6

• x = -3.25

• x = -32/7

• x = -16/7

Answer explanation

To solve the equation, we need to isolate the variable x. Subtracting 37/7 from both sides gives us 2x = 5/7 - 37/7, which simplifies to 2x = -32/7. Dividing both sides by 2, we find x = -16/7. Therefore, the correct choice is x = -16/7.

Solve the equation: 0.25x - 0.1 = 0.3

• x = 1.6

• x = 1.8

• x = 2.0

• x = 2.2

Answer explanation

To solve the equation 0.25x - 0.1 = 0.3, we need to isolate the variable x. Adding 0.1 to both sides, we get 0.25x = 0.4. Dividing both sides by 0.25, we find x = 1.6. Therefore, the correct choice is x = 1.6. This answer satisfies the given equation and is the solution we were looking for.

Solve the equation: 2.5x - 0.8 = 1.7

• x = 1

• x = 2

• x = 3

• x = 4

Answer explanation

To solve the equation 2.5x - 0.8 = 1.7, we need to isolate the variable x. First, we can add 0.8 to both sides of the equation to eliminate the constant term. This gives us 2.5x = 2.5. Next, we divide both sides of the equation by 2.5 to solve for x. The solution is x = 1. Therefore, the correct choice is x = 1. This answer satisfies all the given conditions and provides a clear explanation of the solution to the equation.
