Question

Cx+5c=7c solve for x assume c doesn't equal 0

Answer 1

Because we've assumed
`c \\eq 0`, we can safely divide by
`c` (if
`c` could equal zero, we would have to account for the case in which doing so would be to divide by zero). Hence, we have:


`\begin{aligned} x+5=7 \end{aligned}`

Subtracting
`5` from both sides gives
`x = \boxed{2}`.
