Please help me with this

Zanzabum

Answer:

−4y+32

Step-by-step explanation:

Let's solve for x.

−9

x+8

Step 1: Flip the equation.

−9

x+8=y

Step 2: Add -8 to both sides.

−9

x+8+−8=y+−8

−9

x=y−8

Step 3: Divide both sides by (-9)/4.

−9

y−8

−9

−4y+32

I think this is the right answer.

$2\dfrac{1}{5}+1\dfrac{1}{10}=2+\dfrac{1}{5}+1+\dfrac{1}{10}=(2+1)+\left(\dfrac{1}{5}+\dfrac{1}{10}\right)\\\\=3+\left(\dfrac{1\cdot2}{5\cdot2}+\dfrac{1}{10}\right)=3+\left(\dfrac{2}{10}+\dfrac{1}{10}\right)=3+\dfrac{2+1}{10}=\boxed{3\dfrac{3}{10}}$
