Question

Write a rule that you can use to solve addition equations without using models or drawing

Answer 1

the simple rules in adding equation is

- simplify like terms first
- then get one variable on one side of the equation
- then solve the rest

Answer 2

Addition equation means the equation which involves addition as an operation on both side of equality.

As, you don't have to use models or Drawing to solve the equation or find the value of the variable

So, with using that tool ,follow elementary rule of addition

That is ,

x = 5+11

x=16

Here we have added two like terms which are constants on RHS,to get the result.

→, x+2x=6

3 x=6

x=2

Added two like terms which are variables on the left and got the result.
