Answer 1

If Micah was charged $62.82 for electricity last month, then we can say that y=$62.82
You need to find 'x'
-----------------
Using the given equation you'll have
y = $0.10x + $2.82
$62.82 = $0.10x + $2.82
$62.82 - $2.82 = $0.10x
Compute for x

Answer 8

$62.82 - $2.82 = $0.10x
$60 = $0.10x
Divide the whole equation with $0.10
$60/$0.10 = $0.10x/$0.10
x = ?
