Answer:

-18b^8.

Step-by-step explanation:

To simplify an expression, we combine the elements that are similar (look the same).

So, it we have -20b^8 + 2b^8, we see that there are 2 terms with b^8.  We need to simplify them.

So, we have -20b^8 + 2b^8, that addition leaves -18b^8.

-18b^8 cannot be simplified more.

One number is 2 more than 3 times another. Their sum is 22. Find the numbers.
ivolga24 [154]
Make a system of equations.

\sf~x=3y+2
\sf~x+y=22

Re-arrange the 2nd equation:

\sf~x+y=22

Subtract y to both sides:

\sf~x=-y+22

Plug in -y + 22 for 'x' in the first equation.

\sf~x=3y+2

\sf~-y+22=3y+2

Subtract 3y to both sides:

\sf~-4y+22=2

Subtract 22 to both sides:

\sf~-4y=-20

Divide -4 to both sides:

\sf~y=\boxed{\sf5}

Plug this into any of the two equations to find 'x':

\sf~x+y=22

\sf~x+5=22

Subtract 5 to both sides:

\sf~x=\boxed{\sf17}

So one of the numbers is 5 and one of them is 17.
