What’s the answer to m/3-2m/5=1/5

natta225 [31]

Answer:

m = - 3

Step-by-step explanation:

$\frac{m}{3} - \frac{2m}{5} = \frac{1}{5}$

It is much easier to work with whole numbers, compared to fractions, hence one should remove the denominator of the fraction. This can be done by multiplying by the LCM (least common multiple). In this case, it is fairly obvious that the LCM of 3 and 5 is 15. Therefore multiply the entire equation by 15.

$15*\frac{m}{3} - 15*\frac{2m}{5}=15*\frac{1}{5}$

Simplify

$5m-6m=3$

$-m=3\\m=-3$

HELP!!!!!!!!!

wel

Answer:

$y=-\frac{2}{3} x+4$

Step-by-step explanation:

move the variable to the right(-2x) and change the sign(2x now) -3y=-12+2x then change the signs (-3y is 3y , -12 is 12 and then 2x becomes -2x again) then divide both sides of the equation by 3 so 12÷3=4 and -2x÷3= $-\frac{2}{3} x$ then you're going to use the commutative property to reorder the terms . so your answer is $y=-\frac{2}{3} x+4$
