How to solve 3x - 4 = 11+10

x = 25/3 or 8.333333

Step-by-step explanation:

you add 11 to 10 to get 21

3x-4=21

add 4 to both sides, which will cancel out the (-4)

3x=25

divide each term by 3 to get x by itself

3x/3 = 25/3

you will then get x=25/3

Simplifying

3x + - 4 = 11 + 10

Reorder the terms:

-4 + 3x = 11 + 10

Combine like terms: 11 + 10 = 21

-4 + 3x = 21

Solving

-4 + 3x = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 3x = 21 + 4

Combine like terms: - 4 + 4 = 0

0 + 3x = 21 + 4

3x = 21 + 4

Combine like terms: 21 + 4 = 25

3x = 25

Divide each side by '3'.

x = 8.333333333

Simplifying

x = 8.333333333
