How do you solve `20=3x-1`

First, add 1 to each side to undo subtraction.

`20+1=3x-1+1`

`21=3x`

Divide both sides be 3 to undo x being multiplied by 3.

`21/3="3x"/3`

`7=x`

``Therefore, the solution is x = 7.

First, you would add 1 to both sides, as such:

20 = 3x - 1

+1 +1

21 = 3x

Then, divide each side by 3, getting:

7 = x

So, 7 is the solution to the equation

Question:-

20= 3x-1

Solving for value of x....

Solution:-

20 = 3x - 1

Transferring -1 to LHS

20 + 1 = 3x

21 = 3x

X = 21/3

x = 7

Hence solved.....

This is how i'll solve the following equation:

20=3x-1

20+1=3x

21=3x

21/3=x

7=x

**x=7**

20=3x-1

move like terms to the same side by adding 1

20 + 1 = 3x - 1 + 1

combine

21 = 3x

since were are trying to get x alone we divide by 3

21/3 = 3x/3

7=x

x = 7 is the answer.

20 = 3x - 1

To solve this equation we have to try to get " x " all by itself . In order to do that , we should add 1 to both sides .

By adding 1 to both sides , you should get .

21 = 3x now to get " x " by itself , we have to divide by 3 on both sides .

By dividing by 3 on both sides , you should get .

7 = x which is your answer , as you can see " x " is all by itself on the right side .

To solve for x, you have to get x by itself on one side of the equals sign.

20=3x-1

To start off, add 1 to both sides. The ones on the right cancel and you are left with

21=3x

Now, to undo the multiplication, you need to divide both sides by 3. This cancels the threes on the right and you are left with

**x=7**
