Question

4-b =2-a
what the answer
​

Answer 1

Solve for b: b = 6 - a

Solve for a: a = 6 - b

Explanation:

There are two ways we can solve this, solve for a and solve for b.

Lets solve for b first

`4-b=2-a`

Add 4 on both sides

`b=2-a+4`

Simplify

`b=6-a`

Now lets solve for a

`4-b=2-a`

Flip the equation

`2-a=4-b`

Add 2 on both sides

`a=4-b+2`

Simplify

`a=6-b`
