- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y - 3x = 1
2y - x = 12
<u>Step 2: Rewrite Systems</u>
y - 3x = 1
- Add 3x on both sides: y = 3x + 1
<u>Step 3: Redefine Systems</u>
y = 3x + 1
2y - x = 12
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2(3x + 1) - x = 12
- Distribute 2: 6x + 2 - x = 12
- Combine like terms: 5x + 2 = 12
- Isolate <em>x</em> term: 5x = 10
- Isolate <em>x</em>: x = 2
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 2y - x = 12
- Substitute in <em>x</em>: 2y - 2 = 12
- Isolate <em>y </em>term: 2y = 10
- Isolate <em>y</em>: y = 5
Answer:
1) x= 3/2= 1 1/2
2) x= 2/3
Step-by-step explanation:
1)How many times as heavy as Whiskers is Piglio?
a) Write a multiplication equation for the question.
2 2/3 kg * [x]= 4kg
b) Write a division equation for the question.
4/ 2 (2/3) = x
c) Is the answer greater than 1 or less than 1?
Ans) Greater than 1
d) Find the answer
4/ 8/3= x
x= 3/2= 1 1/2
Pigilo is 1 1/2 times as heavy as whiskers
2)How many times as heavy as Piglio is Whiskers?
a) Write a multiplication equation for the question.
4 kg * [x]= 2 2/3 kg
b) Write a division equation for the question.
2 (2/3)/4 = x
c) Is the answer greater than 1 or less than 1?
Ans) Less than 1
d) Find the answer
8/3/4= x
8/3 * 1/4= x
2/3= x
Whiskers is 2/3 times as heavy as Pigilo.
