Think of it this way. You have 5 apples. You eat 2. How many do you have left? Three. How? Well, you took away two from five, or you subtracted them (5-2) and got 3. We will do the same here.

If it’s the decimal places that confuse you, fear not. You subtract them just the same as you would normal numbers. I added a picture and labelled which numbers you subtract from which to make it easier if that’s the problem. Hope this helped.

The answer is $12.30 :)

Eight times a number plus five another number is -13. The sum of the two numbers is 1. What are the numbers?
Pani-rosa [81]
Eight *(a number) plus 5*(another number) is -13.

translates to:

8(x) + 5(y) = -13

The sum of (the number) and (the other number) is 1.

translates to:

(x) + (y) = 1


We have a system of two equations involving two unknowns: x and y.

\rm 8x+5y=-13\\
~~x+~~y=~~~~1

We can easily solve the system using Substitution or Elimination. Let's use Elimination this time.

We'll multiply the second equation by -8 so that the x's match up.

\rm ~~~8x+5y=-13\\ -8x-8y=-8

When we add the equations together, the x's will fall out of the equation, summing to zero. The 5y and -8y will sum to -3y and the right hand side will sum to -21.

\rm -3y=-21

Divide by -3,

\rm y=7

Plug back into one of your original equations to find the value of x,

\rm x+y=1\\
x+7=1

Subtract 7,

\rm x=-6
