• We have the enunciation, now we can solve.
♦ We note :
- t, the price of the table;
-c, the price of a chair:
3t+2c=1850 }
t=c+75 } =>
=> 3(c+75) +2c=1850
3c+225+2c=1850
5c=1850-225
5c=1625
c=1625:5
c=341=> t=341+75 = 476 .
Step 1: Write down the decimal divided by 1.
<span>Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal, then use 100, if there are three then use 1000, etc.) </span>

Fractions can be converted into decimals and mean the exact same thing
Answer:
Solution is (-3, 0). Lincoln.
Step-by-step explanation:
a. Lincoln's method: His an error was on the third line.
When distributing the 5 over the parentheses he did not multiply the -y by the 5.
He wrote -y while it should be -5y.
Claire's method: Mistake on line 3. She incorrectly distributed the negative over ( -3 - x) . Correct is 3 + x not 3 - x.
b. The correct solution is (-3, 0) which Lincoln got, just by luck, because if we substitute these values into the 2 equations they fit:
5(-3) - 0 = -15.
-3 + 0 = -3.
