Derick solves the problem below.

Mathematics
1 answer:
Gala2k [10]4 years ago
3 0

As it is proved that the equation has no solution, Derick is correct

Step-by-step explanation:

Given

-3(4n + 2) = -4n + -2 (4n - 6)

We have to solve the equation in order to check if Derick was solved the equation correctly or not.

So,

Applying distributive property first

-12n -6 = -4n -8n +12\\-12n-6 = -12n+12\\-12n+12n-6 = 12\\-6 = 12

As the variable is already cancelled in the equation there is no unique solution.

In order for an equation to have infinite solutions the constant on both sides of equation should be same which is not the case in the given equation

So,

As it is proved that the equation has no solution, Derick is correct

If person A earns $51000 more than person b. if total salaries are $304250. find salaries of a nd b
Dafna11 [192]
X + y = 304,250
x = y + 51,000

Plug in (y+51,000) for x into the first equation

y+51,000+y = 304,250
Subtract 51,000 from both sides.
2y = 253,250
y = 126,625

Plug y into second equation

x = 126,625 + 51,000
x =177,625

Person A : 177,625
Person B : 126,625
