What's the answer -5+ 8x - 9 = 3x+3)

Vika [28.1K]

We collect like terms
8x - 3x = 3 + 5 + 9
This is bcos if a (-) sign crosses the equals sign it becomes a (+), and if a (+) sign crosses the equals sign it becomes (-)
We the have
5x = 17
Divide both sides by 5
x = 17/5
x = 3.4

$y = \frac{1}{4} {x}^{4} + \frac{5}{2} {x}^{2} - 18x + k$

Step-by-step explanation:

$dy = ( {x}^{3} + 5x - 18)dx$

Integrating the above expression, we get

$y = \int( {x}^{3} + 5x - 18)dx$

$= \frac{1}{4} {x}^{4} + \frac{5}{2} {x}^{2} - 18x + k$

where k is the constant of integration
