If you would like to solve 7x + 9 = 6x - 5 for x, you can do this using the following steps:
<span>7x + 9 = 6x - 5
</span>7x - 6x = -5 - 9
x = - 14
The correct result would be x = - 14.
Answer:
The minus sign between the two fractions was not distributed correctly.
Step-by-step explanation:
The error made in this solution of rational fractions' subtraction is that the minus sign between the two terms will change the signs of numerator of second fraction so the numerator in the answer will be 3.
The correct solution is:
Hence,
The error was in the last step of subtraction.
So 13x5=65 and 7*6=42, add them up and get 107. So, Paul saved $107 for 11 weeks
