[ (12 - n)/7 ] = -1
12- n = -7
-n = -19
n = 19
Answer:
Step-by-step explanation:
3(5 + 6) = 3(11) = 33
or u could do it this way..
3(5 + 6) = 3(5) + 3(6) = 15 + 18 = 33
The question is an illustration of solving equations using estimates.
The student's strategy makes sense because he uses estimation to solve the given equation
The correct sequence of equation is as follows:
We have:

Add 0 to the equation

Express 0 as 1 - 1


Add another 0

Express 0 as 3 - 3


Rewrite as:

Solve
