Question

Write and solve an equation that represents the following:

Twenty more than a number is eighteen

Answer 1

the equation is
20+a=18

subtract 20 from both sides using additive property that leaves you with

a= -2

Answer 2

Salutations!

Let the number be
`x`

The equation would be:
`x+20=18`

Lets solve this!

We need to always keep the variables aside, and the numbers aside.


`x=20-18`


`x=2`

Hope I helped (:

Have a great day!
