Hi,

For this question, we need to solve this inequality just like we were solving an equation for the variable y alone. Therefore, we first need to subtract 7y from both sides of the inequality to get:

-3 < 3y + 9

Now, subtract 9 from both sides of the inequality to get y on one side of the inequality to get:

-12 < 3y

Next, notice that we need to isolate for y alone by dividing both sides by 3 to get:

FINAL ANSWER:

-4 < y

I hope that helps you out! Please let me know if you have any other questions!

Sincerely,

Andrew

7y-3 < 10y + 9
-3 < 3y + 9
-1 < y + 3 (factor out 3)
-4 < y

Y does not equal anything. This equation means that Y is larger than -4. It covers the whole top of the graph above y = -4. Nothing below -4 is in the solution.

7y - 3 < 10y + 9
7y - 10y -3 < 10y - 10y + 9
-3y -3 < 0 + 9
-3y -3 + 3 < +9 +3
-3y + 0 < 12
-3y / -3 > 12 / -3
y > -4
therefor
values of y can be for this equation
y = (-3,-2,-1,0,1,...,+∞)

7y-3<10y+9

solution:

-3 - 9 < 10y - 7y

-12 < 3y

-4 < y is the answer.

Operate like solving an equation (with one exception shown below)

7y -3 < 10y + 9

7y < 10y + 12

-3y < 12

y > - 4

Note that if you multiply or divide both sides by a negative number, the sense of the inequality reverses.

Solve for y on one side and everything else on the other:

7y - 3 < 10y + 9

7y < 10y + 12

-3y < 12

y < -4

ok well first move the 7y over to the right side of the equation
so you then have -3<3y+9 then carry the 9 over to the left side so you then have -12<3y then you divide by the 3 so -4

7y - 3 < 10y + 9
-3y < 12
y > -4

2007-11-30 12:25:16 · answer #9 · answered by Chino E 1 · 2 3

7y-3 < 10y + 9
10y + 9 > 7y-3
10y-7y > -3-9
3y > -12
y > -12/3
y > - 4
