Explanation:

26. What is the solution for the equation 2x + 5 = 11?

x = 3
x = 2
x = 4
x = 6
Explanation:

Subtract 5 from both sides to isolate x, then divide by 2 to solve for x. x = 3.

27. Solve for x: 3(x - 2) = 15

x = 7
x = 5
x = 10
x = 3
Explanation:

Distribute the 3 first, then isolate x by dividing by 3. x = 7.

28. If 2x + 4 = 16, what is the value of x?

x = 8
x = 6
x = 5
x = 7
Explanation:

Subtract 4 from both sides, then divide by 2 to solve for x. x = 6.

29. What is the solution to the equation 5x - 3 = 22?

x = 6
x = 4
x = 3
x = 5
Explanation:

Add 3 to both sides, then divide by 5 to solve for x. x = 5.

30. If 4(x + 2) = 20, what is the value of x?

x = 6
x = 7
x = 5
x = 4
Explanation:

Divide both sides by 4 first, then isolate x by subtracting 2. x = 4.

31. Solve for x: 6x - 10 = 26

x = 5
x = 7
x = 6
x = 8
Explanation:

Add 10 to both sides, then divide by 6 to solve for x. x = 6.

32. If 3x - 7 = 8, what is x?

x = 3
x = 4
x = 5
x = 6
Explanation:

Add 7 to both sides, then divide by 3 to solve for x. x = 5.

33. What is the solution to the equation 2(x + 3) = 12?

x = 4
x = 2
x = 6
x = 3
Explanation:

Start by distributing the 2, then subtract 6 from both sides and divide by 2 to find x. Therefore, x = 3.

34. Solve for x: 2x - 4 = 10

x = 8
x = 6
x = 7
x = 7.5
Explanation:

Adding 4 to both sides gives 2x = 14. Dividing both sides by 2 gives x = 7.

35. What is the solution to the equation 4(x + 3) = 28?

x = 4
x = 5
x = 6
x = 7
Explanation:

Expanding the equation gives 4x + 12 = 28. Subtracting 12 from both sides gives 4x = 16. Dividing both sides by 4 gives x = 4.

36. Solve for x: 5(x - 2) = 25

x = 8
x = 10
x = 9
x = 7
Explanation:

Expanding the equation gives 5x - 10 = 25. Adding 10 to both sides gives 5x = 35. Dividing both sides by 5 gives x = 7.

37. Solve for x: 5(x - 1) = 44

x = 10
x = 11
x = 9
x = 12
Explanation:

Expanding the equation gives 5x - 5 = 44. Adding 5 to both sides gives 5x = 49. Dividing both sides by 5 gives x = 9.
