Question

How would I solve x-0.1x+0.07(x-0.1x)=69.62

Answer 1

add and subract all of the coefficients of your x and then divide 69.62 by that coefficient

Answer 2

multiply both sides by 1000, thus you'd end up with \(\bf x-0.1x+0.07(x-0.1x)=69.62\qquad \textit{both sides}\times 1000\\ \quad \\
x-0.1x+0.07(x-0.1x)=69.62\\ \quad \\\implies x-0.1x+0.07x-0.007x=69.62\\ \quad \\
1000x-100x+70x-7x=69620
\)

then solve for "x"
