Answer:
x = 3
Step-by-step explanation:
Solve for x:
4 x + 3 x - 6 x - 5 + 8 + 11 = 3×4 + 5
3×4 = 12:
4 x + 3 x - 6 x - 5 + 8 + 11 = 12 + 5
Grouping like terms, 4 x + 3 x - 6 x - 5 + 8 + 11 = (-6 x + 3 x + 4 x) + (8 + 11 - 5):
(-6 x + 3 x + 4 x) + (8 + 11 - 5) = 5 + 12
-6 x + 3 x + 4 x = x:
x + (8 + 11 - 5) = 5 + 12
8 + 11 - 5 = 14:
x + 14 = 5 + 12
5 + 12 = 17:
x + 14 = 17
Subtract 14 from both sides:
x + (14 - 14) = 17 - 14
14 - 14 = 0:
x = 17 - 14
17 - 14 = 3:
Answer: x = 3
