Answer:

-19, -18, -17

Step-by-step explanation:

1. To find the sum of three consecutive integers, we can use the formula x + x + 1 + x + 2, where x = first term. As you can see from the formula, + 1 is the next term, and + 2 is the following term after that.

2. (Solving)

Step 1: Combine like terms.

  • (x + x + x) + (1+2) = -54
  • 3x + 3 = -54

Step 2: Subtract 3 from both sides.

  • 3x + 3 - 3 = -54 - 3
  • 3x = -57

Step 3: Divide both sides by 3.

  • \frac{3x}{3} = \frac{-57}{3}
  • x = -19

3. Now that we know our first term is -19, let's apply it to x + x + 1 + x + 2.

  • (-19) + (-19+1) + (-19+2)
  • -19 + (-18) + (-17)

4. Okay, so we got that the integers are -19, -18, and -17. Let's check if these numbers sum to -54.

  • -19 - 18 - 17
  • -37 -17
  • -54

Therefore, the integers are -19, -18, and -17.

-2<em>x</em> + 6<em>y</em> = -38

3<em>x</em> - 4<em>y</em> = 32

To solve by elimination, multiply the top equation by 3 and the bottom equation by 2.

3(-2<em>x</em> + 6<em>y</em> = -38) --> -6<em>x</em> + 18<em>y</em> = -114

2(3<em>x</em> - 4<em>y</em> = 32) --> 6<em>x</em> - 8<em>y</em> = 64

Add the equations.

-6<em>x </em>+ 18<em>y</em> = -114

6<em>x</em> - 8<em>y</em> = 64

+_____________

0 + 10<em>y</em> = -50

10<em>y</em> = -50

<em>y</em> = -5

Substitute -5 for y into one of the original equations to find x.

3<em>x</em> - 4<em>y</em> = 32

3<em>x</em> - 4(-5) = 32

3<em>x</em> + 20 = 32

3<em>x</em> = 12

<em>x</em> = 4

Check work by plugging the <em>x</em>- and <em>y</em>-values into both of the original equations.

-2<em>x</em> + 6<em>y</em> = -38

-2(4) + 6(-5) = -38

-8 - 30 = 38

38 = 38


3<em>x</em> - 4<em>y</em> = 32

3(4) - 4(-5) = 32

12 + 20 = 32

32 = 32

Answer:

<em>x</em> = 4 and <em>y</em> = -5; (4, -5).
