-8x2(x+8)=8(2+6) how do i solve this and 4n+3/2=2n-5/1?

Marat540 [252]

1) $-8x^2\left(x+8\right)=8\left(2+6\right)$

$-8x^3-64x^2=64$

$-8x^3-64x^2-64=64-64$

$-8x^3-64x^2-64=0$

$-8x^2+0.97035\dots x-7.88051\dots \approx \:0$

$x\approx \:-8.12129\dots$

2) $4n+\frac{3}{2}=2n-\frac{5}{1}$

$4n+\frac{3}{2}=2n-5$

$4n+\frac{3}{2}-\frac{3}{2}=2n-5-\frac{3}{2}$

$4n=2n-\frac{13}{2}$

$4n-2n=2n-\frac{13}{2}-2n$

$2n=-\frac{13}{2}$

$\frac{2n}{2}=\frac{-\frac{13}{2}}{2}$

$n=-\frac{13}{4}$

1.8y is the answer because first you do 3/4y into a decimals number and then it’s 0.75 then I times it by 2.4 which is 1.8y
