✔ 最佳答案
5y < 37
y < 37/5
2008-02-10 2:07 pm
5y-6+6< 31+6 (adding 6 to both sides)
5y+0< 31+6
5y< 37
y/5< 37/5 (divding by 5 both sides)
we get, y< 37/5

hence value of y<7.4

it's so simple..!!!

you're able to desire to convey each and every of the numbers to the staggering section and letters to the left, with the equivalent sign in between, while numbers and letters circulate over to the different element of the equivalent sign, they alter from being beneficial to destructive, or vise versa. Then grab a calculator or do the math on your head for each section untill you have one quantity on the two aspects of the equivalent sign after which take the quantity without the letter and divide it via the quantity with the letter and the you're left with y= the respond. observe that if its in basic terms a y, it incredibly ability it 1y. So it may circulate like this: 5y+y-7y+4y=30+7-31, 3y=6, y=2 Sorry if it isn't any longer the wonderful explination!

5y-6<31
+6 +6 ---add 6 to both sides
_______
5y<37 ---the 6s on the left side cancel out
5y/5 < 37/5 ---divide both sides by 5

and you get:
"y= 7.4"

5y less than 31+6
5yless than37
ie, yless than37 divided by 5
yless than 7.4

With linear inequalities, we can treat the inequality sign the same as an equal sign. Therefore:

5y-6<31
5y<31+6
5y<37
Therefore, y<37/5

two solve for this type of equation, make sure you have to solv e for y so y should be either side alone,
5y-6<31
5y<31+6 (add 6 from both side)
5y<37
y<37/5( divide by 5 from both side)
y<7.4 ans.

good luck,

5y-6<31 => 5y<31+6 => 5y <37 => y<37/5
2008-02-10 2:13 pm
5y - 6 < 31
5y < 31 + 6
5y < 37
y < 37/5
y < 7 2/5 or 7.4
