Which equation can be used to find two numbers such that twice the first equals three times the second and three times their dif
Musya8 [376]
Let the numbers be a and b and b>a

2a=3b  and 3(b-a)=2(b-a)+13

Solving the first for a:

2a=3b

a=3b/2, now using this value of a in the second equation gives you:

3(b-3b/2)=2(b-3b/2)+13  upon performing indicated operations.

3b-9b/2=2b-6b/2+13  making all terms have a common denominator of 2

(6b-9b)/2=(4b-6b+26)/2  multiplying the whole equation by 2

6b-9b=4b-6b+26  combining like terms

-3b=-2b+26  adding 2b to both sides

-b=26  dividing both sides by -1

b=-26, since a=3b/2

a=3(-26)/2

a=-39

So the numbers are -39 and -26

check...

2a=3b becomes:

2(-39)=3(-26)

-78=-78

3(b-a)=2(b-a)+13 becomes:

3(-26--39)=2(-26--39)+13

3(13)=2(13)+13

39=26+13

39=39

correct :P

What should be added to -5/4 to get -1?
nikitadnepr [17]

Answer: 1/4

Step-by-step explanation:

We can actually write an equation to find what should be added to get -1.

-\frac{5}{4}+x=-1

We get this equaiton because the problem asks what should be added to -5/4 to get -1. We put x in place to see what number fits. X is being added to the -5/4.

x=-1+\frac{5}{4}

x=-\frac{4}{4}+\frac{5}{4}

x=\frac{1}{4}
