4y-9=15

you need to move the y to one side alone.

Add 9 to both sides, then divide each side by 4

Isolate y

does any body knows how to solve and graph inequalities? ............... PLEASE HELP ME!, I REALLY NEED THIS!, THANX.

x=6

x=6. it's pretty simple haha.

4y-9=15

4y=15-9
4y=6
y=4/6
y=2/3

x=6

To solve the equation 4y - 9 = 15, we need to isolate the variable y.

Step 1: Start by adding 9 to both sides of the equation to eliminate the -9 term:
4y - 9 + 9 = 15 + 9
This simplifies to:
4y = 24

Step 2: Next, we want to isolate y by dividing both sides of the equation by 4:
4y/4 = 24/4
This simplifies to:
y = 6

Therefore, the solution to the equation is y = 6. To double-check our answer, we can substitute y = 6 back into the original equation:
4(6) - 9 = 15
24 - 9 = 15
15 = 15

As both sides of the equation are equal, we can be confident that y = 6 is the correct solution.
