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
