if 3(5y-8)=7Y what us the value of y?

Answer 1

3(5y-8)=7Y
15y-24=7y
15y-7y=24
8y=24
y=24/8
y=3

Answer 2

y=3

Answer 3

3(5y-8)=7y

1.) Multiply 3 by the numbers in the parenthesis.

Then you have this.

15y-24=7y

2.) Subtract 7y to get y by itself on the left side. Add 24 to the other side.

15y-24=7y
-7y +24 -7y +24

3.) Subtract 15y-7y which equals 8y, then on the other side have 24.

8y=24

4.) Divide both sides by 8 to get y by itself.

8y=24

5.) Final answer is 3

Hoped I helped. I know what I wrote is not easy to follow. 3 is the answer though.

Answer 4

Step a million: set up the help into equations. enable the intergers be x and y. because of the fact the sum of the two is comparable to 280, we are able to set it up as follows: x + y = 280 Now we are instructed that as quickly as we divide the integer "x" via "7", the respond is the integer "y". x/7 = y I hate fractions. enable's artwork this 2d equation algebraically so as to do away with the fraction. x/7 = y (enable's multiply the two sides via 7) (7)(x/7) = y (7) x = 7y ok, now, my 2 equations are: x + y = 280 and x = 7y Step 2: substitute the 2d equation into the 1st. x + y = 280 (7y) + y = 280 7y + y = 280 Step 3: Simplify the equation. 7y + y = 280 8y = 280 Step 4: resolve for "y" 8y = 280 y = 280 ÷ 8 y = 35 (<==answer!!) ------ Bonus question: What might "x" be equivalent to? in simple terms substitute the "y" answer which you purchased into ANY of the two equations we've been given in "Step a million". x = 7y x = 7(35) x = 245 (<==answer!!) desire I helped!

Answer 5

3(5y-8)=7Y
Remove brackets:
15y - 24 = 7y
Gather like terms:
15y - 7y = 24
Simplify:
8y = 24
y = 24/8
y = 3

Answer 6

I'll show you how to do it with different numbers so that it isn't cheating.

4(2y-5)=6y

Multiply the 4 across the left side of the equation.

4(2y)-4(5) is
8y-20

Now you need to get both y's on the same side of the equation. To do that subtract the term w/y from both sides.
8y -20=6y
-8y =-8y
_________
-20 = -2y

Now you need to get y alone. To do that divide both sides by the number preceding the y.

-20/-2 = -2/-2y

Because 2 negatives equal a positive the answer is
10 = y

I hope this helps. I think it's better to get to know the process than cheat and just get the answer. Use this process with your numbers and you will get the right answer.

Answer 7

I got y=3

Answer 8

15y - 24 = 7y
-24 = -8y
3 = y

Answer 9

4.

if you distribute you get 15y-24=7y
then by subtraction you get 8y-24=0
by addition you get 8y=24
divide and you get y=4

Good Luck.

Answer 10

y=3

3(15-8)=21
3(7)=21
21=21
