Answer:

x = 3

Explanation:

29 - 3x = 5x + 5

You want to have the variable of x on one side of the equation, so add 3x to both sides.

29 = 8x + 5

You want to isolate the variable of x, so subtract 5 from both sides.

24 = 8x

You want the variable x on its own, so divide both sides by 8.

3 = x

Check your answer by plugging x back into the original equation.

29 - 3(3) = 5(3) + 5

Solve.

29 - 9 = 15 + 5

20 = 20

Your answer is correct!
