Answer:
x=6
Step-by-step explanation:
5x-3=2x+15
5x-2x-3=15
3x-3=15
3x=15+3
3x=18
x=18/3
x=6
Its False. addition and subtraction, Multiplication and division are inverse operations.
Answer: 5a + 5b + 5 - x(a + b)
Step-by-step explanation:
(a + b + 1)2 – (a + b + 1)(x - 2) + (a + b + 1)
2a + 2b + 2 - (ax - 2a + bx -2b -2) + (a + b + 1)
2a + 2b + 2 - ax + 2a - bx +2b +2 + a + b + 1
5a + 5b + 5 - x(a + b)
The mistake done is in multiplying the numerator values after Taking LCM.
Correct answer is
Step-by-step explanation:
We will first solve the expression and then identify the error.
Solving:
Finding LCM of (x-2) and (x+1) we get (x-2)(x+1)
So, the mistake done is in multiplying the numerator values after Taking LCM. x+1-(x-2) we get x+1-x+2 because (-)*(-) = + and (-)*(+)= -. So, we get
x-x+1+2 we know that x-x=0 and 1+2=3
So, correct answer is
