No. 5+9=14. 7+9=16, therefore x=7.

x = 5 ========== 3x - 9 = -2x + 16 Balance the equation by adding 2x and 9 to both sides: 3x + 2x = 16 + 9 5x = 25 Divide both sides by 5 to get value for x: x = 5
sqrt(x) + 5 = 9 so sqrt(x) = 9 - 5 = 4 so x = 4^2 = 16
If the equation is (-9-7)x = -5, then x= .3125 or 5/16 If the equation is -9-7x = -5, then x = -.571428 or -4/7
