1/ 3 (y+7)=3(y−1) help me

Mathematics
1 answer:
Alex_Xolod [135]4 years ago
5 0

Answer:

y=2

Step-by-step explanation:

1/3(y+7)=3(y-1)

1) Distribute 1/3 to y+7, and distribute 3 to y-1:

1/3y+7/3=3y-3

2) Add 3 to both sides:

1/3y+16/3=3y

3) Subtract 1/3y from both sides:

16/3=8/3y

4) Multiply both sides by the reciprocal of 8/3: (3/8)

y= 48/24

5) Simplify:

y=2

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The several people are sitting evenly spaced around a circular table and the positions are labelled 1, 2, 3 and so on.

The people at positions 3 and 15 are directly opposite each other.

Then the number of the people are sitting at the table will be

1 is opposite to 13

2 is opposite to 14

3 is opposite to 15

Similarly, 12 will be opposite to 24.

Then the number of the people are sitting at the table will be 24.

Solve the equation. 2x − 3 4x = 21 x = −12 x = −6 x = 4 x = 6
luda_lava [24]

The solution of the equation after solve the equation, 2x − 3 4x = 21 is 4. Option 3 is correct.

<h3>How to obtain the solution of equation?</h3>

To obtain the solution of an equation, the similar terms should be arranged together and then mathematical operation need to be performed to simplify it.

The equation which is provided to solve is,

2x - 3 +4x = 21

To solve this equation, arrange the like terms as,

2x - 3 +4x = 21\\2x +4x - 3 = 21\\6x-3=21

Add number 3 both side of the equation as,

6x-3+3=21+3\\6x=24

Divide both side of the equation with number 6, we get,

x=\dfrac{24}{6}\\x=4

Hence, the solution of the equation after solve the equation, 2x − 3 4x = 21 is 4. Option 3 is correct.
