Question

a student solves the equation below:

\\-4 - x = -9\\

which equations are the student likely to have as part of their work?

select all that apply.

a \\(-x = -13\\)
b \\(-x = -5\\)
c \\(x = 13\\)
d \\(x = 5\\)
e \\(x = -5\\)
f \\(x = -4\\)
g \\(-x = 5\\)

Explanation:

Write down the starting equation

$$ -4 - x = -9 $$

Isolate the variable term by adding 4 to both sides
