Question #9f747

Answer 1

`b=20`

Explanation:

You will need to get `b` by itself.

You subtract `15` from both sides to get `b` alone.

`15-15+b =35-15`

`b=20`

Answer 2

We'll use transposing method,
remember, in this method if we transfer a number from LHS to RHS or vice versa, it will change from negative to positive and vice versa,
For example,
`10x+2=22`
`10x=22-2`
Notice that 2 in LHS was in positive, though that same 2 when transferred to RHS became negative.
Using the same principals,
`15+b=35`
Here 15 is in positive, so transferring it to RHS, it will become negative,
`b=35-15`
`b=20`
Hope you understood
