Answer:
Value x = 8 make the equation true .
Step-by-step explanation:
Given : 3x = 24.
To find : Which value of x from the set {5, 6, 7, 8} makes this equation true?
Solution : We have given 3x = 24.
The equations are true when the Left hand side and right hand side of the equation are equal.
Then,
For x = 8 .
3 ( 8) = 24
24 = 24 .
Hence,
Left hand side = Right hand side.
Therefore, Value x = 8 make the equation true .
Answer: see below
Step-by-step explanation
Let 2 + a = 11 x
Let 35 - b = 11 y
Where x and y are any unknown integer
subtract the two equations
- 33 + a + b = 11 (x+y)
a+ b = 11 (x+ y) +33
a+ b = 11 (x+y) + 3 (11)
a+ b = 11(x+ y+3)
Which proves that a+b is a factor of 11
