Does (-2x+y=6)+ (y-2x=4) have no solution?

1 answer:

4 0

Assuming you are asking

does -2x+y=6 and y-2x=4 have a solution

look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values

there is no solution
these 2 lines are paralell

NO SOLUTION

1 3/4 − 4/5 = 35 twentieths − what fraction??? Plss help will give brainliest :)

let's firstly convert the mixed fractions to improper fractions and then to do away with the denominators, let's multiply both sides by the LCD of all denominators.

$\stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{7}{4}-\cfrac{4}{5}=\cfrac{35}{20}-\boxed{?}\implies \stackrel{\textit{multipling both sides by }\stackrel{LCD}{20}}{20\left( \cfrac{7}{4}-\cfrac{4}{5} \right)=20\left( \cfrac{35}{20}-\boxed{?} \right)} \\\\\\ 35-16=35-20\boxed{?}\implies 19=35-20\boxed{?}\implies -16=-20\boxed{?} \\\\\\ \cfrac{-16}{-20}=\boxed{?}\implies \cfrac{4}{5}=\boxed{?}$
