Answer:
x=7
Step-by-step explanation:
Solve for x:
3 x + x + 5 = 33
x + 3 x = 4 x:
4 x + 5 = 33
Subtract 5 from both sides:
4 x + (5 - 5) = 33 - 5
5 - 5 = 0:
4 x = 33 - 5
33 - 5 = 28:
4 x = 28
Divide both sides of 4 x = 28 by 4:
(4 x)/4 = 28/4
4/4 = 1:
x = 28/4
The gcd of 28 and 4 is 4, so 28/4 = (4×7)/(4×1) = 4/4×7 = 7:
Answer: x = 7
