Answer:

x=7

Explanation:

Solution for 3x-10-x=4 equation:

Simplifying

3x + -10 + -1x = 4

Reorder the terms:

-10 + 3x + -1x = 4

Combine like terms: 3x + -1x = 2x

-10 + 2x = 4

Solving

-10 + 2x = 4

Solving for variable 'x'.

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

Add '10' to each side of the equation.

-10 + 10 + 2x = 4 + 10

Combine like terms: -10 + 10 = 0

0 + 2x = 4 + 10

2x = 4 + 10

Combine like terms: 4 + 10 = 14

2x = 14

Divide each side by '2'.

x = 7

Simplifying

x = 7
