- 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
5)
Based on graph x > -3
Answer: x > - 3 (last one)
6)
m> - 2
So the answer is the last one.
Step 1: <span>Rewrite the decimal number as a fraction with 1 in the denominator.
Step 2: </span>Multiply to remove 10 decimal places. Here, you multiply top and bottom by 10 to the power of 10<span> = 10000000000
Step 3: Find the GCF of 476190476 and 10000000000 </span><span>if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4.

Answer:
2
Step-by-step explanation:
because if -3 was matched up with two before then you have to make it consistent and make sure that the pattern is continous.
