- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
5x - 9y = -26
-2x + 3y = 11
<u>Step 2: Rewrite Systems</u>
-2x + 3y = 11
- Multiply everything by 3: -6x + 9y = 33
<u>Step 3: Redefine Systems</u>
5x - 9y = -26
-6x + 9y = 33
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine 2 equations: -x = 7
- Divide -1 on both sides: x = -7
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 5x - 9y = -26
- Substitute in <em>x</em>: 5(-7) - 9y = -26
- Multiply: -35 - 9y = -26
- Add 35 on both sides: -9y = 9
- Divide -9 on both sides: y = -1
Answer: 321.4167 or about 322 boxes

Answer:
x = 6
Step-by-step explanation:
Since the triangle is equilateral then sides are congruent.
Equate any 2 sides and solve for x
13x + 5 = 8x + 35 ( subtract 8x from both sides )
5x + 5 = 35 ( subtract 5 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
JK = (13 × 6) + 5 = 78 + 5 = 83
KL = (17 × 6) - 19 = 102 - 19 = 83
JL = (8 × 6) + 35 = 48 + 35 = 83
ΔJKL is equilateral with side = 83
The answer is 5 because you would multiply 5 by the 1,000 to get 5,000
