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.
