Consider the system of equations

lyudmila [28]

4)
I:3x+4y=67
II:5x-y=35

to eliminate y when they are added one of the equations must contain -ay and the other +ay (with a being some number)
in this case we have in I already a positive term and in II a negative, but they have different numbers
by using multiplication (property of equations) we can multiply II by 4 so the negative and positive parts match

II*4: 20x-4y=140

when I and 4*II get added this results in
3x+20x+4y-4y=67+140
23x=207

5)
in this case I and II were added which can be seen in the left side of the equation((3x+4y)+(5x-y)=8x+3y), so to get the right side we have to also add the right sides 67+35=102

so the full equation would be:
8x+3y=102

What is 9/10-2/3 in simplest form

Serggg [28]

Answer: The simplified form of above expression is $\frac{7}{30}$

Step-by-step explanation:

Since we have given that

$\frac{9}{10}-\frac{2}{3}\\$

We need to solve the above expression to get the simplified answer:

1) Take the L.C.M. of 10 and 3.

L.C.M. of 10 and 3 = 30

2) Make the denominator 30 for each of the fraction .

$\frac{9}{10}\times \frac{3}{3}=\frac{27}{30}\\\\and\\\\\frac{2}{3}\times \frac{10}{10}=\frac{20}{30}$

3) Take the difference between them:

$\frac{27}{30}-\frac{20}{30}\\\\=\frac{7}{30}$

Hence, the simplified form of above expression is $\frac{7}{30}$
