3X/40 =15
how you subtract these two equations?

Answer 1

If she started out with x, and was left with 15 more than half of what she started with, then

x - x/8 - x/5 - x/10 = x/2 + 15

x = 200

The Elimination Method

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...

Step 2: Subtract the second equation from the first.

Step 3: Solve this new equation for y.

Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
