what do you mean by multi step equation

anonymous · Answer

Harry made a down payment of $525 on his car. This was 30% of the cost, plus $153 tax on his car. How much did the car cost?

anonymous · Answer

First he paid $525, lets call this y
Since y is 30% of the original cost(Lets call it x), plus tax
that means that y = 0.30 * x + 153

anonymous · Answer

Now you are left with the equation
 y = 0.30 * x + 153

where y is 525

We have to solve for x

anonymous · Answer

So we say 

525 = 0.3x + 153
subtract 153 from both sides

372 = 0.3x
divide both sides by 0.3

we have x = $1240
