Question

-[3x+7]=x=19 can somebody solve this

Answer 1

Answer:

Step-by-step explanation:

Simplifying

3x + 7 + x = 19

Reorder the terms:

7 + 3x + x = 19

Combine like terms: 3x + x = 4x

7 + 4x = 19

Solving

7 + 4x = 19

Solving for variable 'x'.

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

Add '-7' to each side of the equation.

7 + -7 + 4x = 19 + -7

Combine like terms: 7 + -7 = 0

0 + 4x = 19 + -7

4x = 19 + -7

Combine like terms: 19 + -7 = 12

4x = 12

Divide each side by '4'.

x = 3

Simplifying

x = 3
