• x = 42

• x = 58

• x = 50

• x = 8

Answer explanation

To solve the equation x + 8 = 50 using the addition principle, we need to isolate x. Subtract 8 from both sides to get x = 42.

• x = -18

• x = -50

• x = -20

• x = -16

Answer explanation

To solve the equation -34 = x - 16 using the addition principle, we need to isolate x. Add 16 to both sides to get x = -34 + 16. Therefore, x = -18.

• x = -43

• x = -7

• x = -25

• x = -18

Answer explanation

To solve the equation -25 = x - 18 using the addition principle, we need to isolate x. Add 18 to both sides to get x = -25 + 18. Therefore, x = -7.

• x = \frac{5}{11}

• x = \frac{9}{11}

• x = \frac{1}{11}

• x = \frac{3}{11}

Answer explanation

To solve the equation, isolate x by subtracting 2/11 from both sides. x = 7/11 - 2/11 = 5/11.

• x = 2.7

• x = 3.7

• x = 6.4

• x = 10.1

Answer explanation

Subtract 3.7 from both sides to isolate x. 6.4 - 3.7 = x. Therefore, x = 2.7.

• x = \frac{1}{2}

• x = \frac{2}{5}

• x = \frac{1}{5}

• x = \frac{3}{10}

Answer explanation

To solve for x, first subtract 1/10 from both sides to isolate x. x = 3/5 - 1/10 = 6/10 - 1/10 = 5/10 = 1/2.

• 13.83

• 14.17

• 13.83

• 14.83

Answer explanation

Subtract 1/6 from both sides to isolate x: x = 14 - 1/6 = 83/6 = 13.83

• 1/3

• 2/3

• 1/7

• 2/7

Answer explanation

To solve the equation, simplify each side separately. On the left side, 1 - 2/7 = 5/7 - 7/7 + 2/3 simplifies to 5/7 - 1 + 2/3. Then, combine like terms to get the final answer.
