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.
To solve the equation:
29x – 2(9x – 0.455) = 10x + 0.525
First, distribute the -2 to the terms inside the parentheses:
29x – 2 * 9x + 2 * 0.455 = 10x + 0.525
29x – 18x + 0.91 = 10x + 0.525
Next, combine like terms on both sides of the equation:
(29x – 18x) + 0.91 = (10x) + 0.525
11x + 0.91 = 10x + 0.525
To isolate the variable x, subtract 10x from both sides of the equation:
11x - 10x + 0.91 = 10x - 10x + 0.525
x + 0.91 = 0.525
Then, subtract 0.91 from both sides:
x + 0.91 - 0.91 = 0.525 - 0.91
x = -0.385
Upon checking your solution, you concluded that it is not equal. It's possible that you made an error during the calculation or there may be another mistake. Double-check your calculations and make sure you accurately performed all the steps. If you're still having trouble, feel free to ask for further assistance.
