Plug in the numbers to the following letters. For example, the equation would be 20+2(3(7)-4(4)) which gives you a final answer of 30
If x = 4 and y = 7 of the following expression: 20 + 2 ( 3 y − 4 x ) then it will gives 30.
What are equivalent expressions?
Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple.
Given,
If x = 4 and y = 7 ,
the following expression: 20 + 2 ( 3 y − 4 x )
Substitue;
20 + 2 ( 3 y − 4 x )
20 + 2 ( 3(7) − 4 (4) )
20 + 2 (5)
20 + 10
