If: x+16 = 9x then x = 2
x=-7
So 17 = 9x, making x = 1 and 8/9
8x + 9x = x(8 + 9) = x(17) = 17x
12x + 17 - (9x - 2)Eliminate parentheses:12x + 17 - 9x + 2Combine the 'x' terms:3x +17 + 2Combine the numerical terms:3x + 19
Presuming 1.2222222 is intended to be 1.2repeating: 1.2222222...=11/9 Presuming 1.77777 is intended to be 1.77777repeating: 1.77777...=16/9 How did we do this? Both work by the same principle, so I'll show how to solve one and you should then be able to solve the other. Let x=1.77777..., then 10x=17.7777.... . Then, 10x - x = 17.7777... - 1.77777..., continuing using algebra: 9x = 17 - 1, 9x = 16 x = 16/9. Eddie O.
If you are looking for the value of x... X=4
3x2 - 9x - 912 = 3(x2 - 3x - 304) = 3(x - 19)(x + 16).
Expressions equivalent to (9x) include (3(3x)), (18 \cdot \frac{x}{2}), and (\frac{27x}{3}). Any expression that can be simplified to (9x) through multiplication or division by non-zero constants is also equivalent.
9x is the lowest common multiple. (9x * 1 = 9x) (x * 9 = 9x)
x-17 = 16-5 x = 16-5+17 x = 28
To solve the equation (9x = 12), you can isolate (x) by dividing both sides by 9. This gives you (x = \frac{12}{9}), which simplifies to (x = \frac{4}{3}). Thus, the equivalent expression for the equation is (x = \frac{4}{3}).
