HINT: (7x) + (2x + 36) = 180º

4. dietrich_harmon

7x + (2x+36) = 180 7x + 2x+36 = 180 9x+36 = 180

5. geerky42

Yeah, NOW solve for the value of x.

Can't you solve for the value of x?

8. geerky42

@dietrich_harmon ???

None. Don't you know how to solve for the value of x?

11. geerky42

OK, so we have the equation: 9x + 36 = 180 In order to find x, we need to isolate x (leave x alone) and this will give you the answer. The variable x needs to be alone, do you know how to make those numbers around x go away and go on other side of the equation?

12. geerky42

Basic algebra isn't hard, really. You can do it.

All you have to do is Isolate x. If you can combine like terms, then you can do algebra.

Simplifying 9x + 36 = 180 Reorder the terms: 36 + 9x = 180 Solving 36 + 9x = 180 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-36' to each side of the equation. 36 + -36 + 9x = 180 + -36 Combine like terms: 36 + -36 = 0 0 + 9x = 180 + -36 9x = 180 + -36 Combine like terms: 180 + -36 = 144 9x = 144 Divide each side by '9'. x = 16 Simplifying x = 16

Go to www.algebrahelp.com there is an algebra calculator all you do is type in your equations. Hope this helps!
