Answer:
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
