Question

The difference of six times a number and 7 is -49

Answer 1

Greetings!

"The difference of six times a number and 7 is -49"...

In number and variables, this would be:
$6x-7=-49$

Add 7 to both sides.
$(6x-7)+7=(-49)+7$
Simplify.
$6x=-42$
Divide both sides by 6.
$(6x)/6=(-42)/6$
Simplify.
$x=-7$

Hope this helps.
