- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -x + 1
2x + 3y = 6
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x + 3(-x + 1) = 6
- Distribute 3: 2x - 3x + 3 = 6
- Combine like terms: -x + 3 = 6
- Isolate <em>x</em> terms: -x = 3
- Isolate <em>x</em>: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -x + 1
- Substitute in <em>x</em>: y = -(-3) + 1
- Simplify: y = 3 + 1
- Add: y = 4
The answer would be:
6x - 7

Answer:
15 hours.
Step-by-step explanation:
We first need to see how much money Rose would earn if she sold the 10 pendents, so we will multiply 4×10.
4×10=40
Now we know, she already has 40 dollars of the 160 dollars she needs.
To find out how much she needs left, we will subtract 40 from 160.
160-40=120
She needs a total of 120 more dollars from working.
To find out how many hours she needs to work, we will divide 120 by 8.
120÷8=15.
In conclusion, she needs to work for at least15 hours to receive enough money.Please help me by marking this brainliest, and giving a thanks!
