Solve.

29x – 2(9x – 0.455) = 10x + 0.525

Give us you thinking on this so we can help you solve the equation. What is it you don't understand about solving this eqution?

29x –2(9x – 0.455) = 10x + 0.525

29x – 18x – 0.91 = 10x + 0.525

11x – 0.91 = 10x + 0.525

-10x -10x

X -0.91 = 0.525

+0.91 =+0.91

X = 1.435

When I check my problem its not equal.

and I don't know what I'm doing wrong.

You made a mistake in the second line. It should be

29x – 18x + 0.91 = 10x + 0.525

(Minus the minus sign in the parentheses is equivalent to a plus)

After that, your steps toward solution were correctly done. Try again.
