2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
- 7X - 2 = 24 - 9X add 9X to both sides 2X - 2 = 24 add 2 to both sides 2X = 26 divide both sides by 2 X = 13 ---------------------check in original equation - 7(13) - 2 = 24 - 9(13) - 91 - 2 = 24 - 117 - 93 = - 93 checks
First sum the terms with x: 9x + (-3)x = 6 x. Then sum the terms without x: -11 + (-13)x = -24. Then 6x - 24 =0 or x = 24/6 = 4
15X - 10 = - 9X + 2 add 9X to both sides 15X + 9X - 10 = - 9X + 9X +2 24X - 10 = 2 add 10 to each side 24X - 10 + 10 = 2 + 10 24X = 12 divide each sides integer by 24 (24/24)X = 12/24 X = 1/2 ------------check in original equation 15(1/2) - 10 = - 9(1/2) + 2 15/2 - 10 = - 9/2 + 2 Now, 10 is 20/2 and 2 is 4/2 15/2 - 20/2 = - 9/2 + 4/2 - 5/2 = - 5/2 ---------------------checks
9x is the lowest common multiple. (9x * 1 = 9x) (x * 9 = 9x)
2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9

24 ; Identify the variable in the equation.5 + 9x = 68a. 5 b. 68 c. x d. 9x
Do you mean: 9x+9 = 4x+24 If so x = 3

- 7X - 2 = 24 - 9X add 9X to both sides 2X - 2 = 24 add 2 to both sides 2X = 26 divide both sides by 2 X = 13 ---------------------check in original equation - 7(13) - 2 = 24 - 9(13) - 91 - 2 = 24 - 117 - 93 = - 93 checks
-7 x -2= 14 24 - 9= 15 So no, it is not equal.
First sum the terms with x: 9x + (-3)x = 6 x. Then sum the terms without x: -11 + (-13)x = -24. Then 6x - 24 =0 or x = 24/6 = 4
15X - 10 = - 9X + 2 add 9X to both sides 15X + 9X - 10 = - 9X + 9X +2 24X - 10 = 2 add 10 to each side 24X - 10 + 10 = 2 + 10 24X = 12 divide each sides integer by 24 (24/24)X = 12/24 X = 1/2 ------------check in original equation 15(1/2) - 10 = - 9(1/2) + 2 15/2 - 10 = - 9/2 + 2 Now, 10 is 20/2 and 2 is 4/2 15/2 - 20/2 = - 9/2 + 4/2 - 5/2 = - 5/2 ---------------------checks
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
9x is the lowest common multiple. (9x * 1 = 9x) (x * 9 = 9x)
