Question

(27-x)+(15+x)=x-24

Answer 1

\( 27 - x + 15 + x = x - 24\\ \Leftrightarrow 42 = x - 24\\ \Leftrightarrow x = 66 \)

Answer 2

(27 - x) + (15 + x) = x - 24

⇔ x - 24 = 42

⇔ x = 66

Vậy x = 66 là nghiệm của pt

Answer 3

tui lam dc roi :((((

Answer 4

(27-x)+(15+x)=x-24

27-x+15+x=x-24

42=x-24

x=42+24

x=66

Tick mik nha!!!

Answer 5

( 27 - x ) + ( 15 + x ) = x - 24

27 - x + 15 + x = x - 24

( 27 + 15 ) + ( - x + x ) = x - 24

42 + 0 = x - 24

=> x = 42 + 24 = 66

Vậy x = 66

Answer 6

\(\left(27-x\right)+\left(15+x\right)=x-24\)

\(27-x+15+x=x-24\)

\(\left(27+15\right)+\left(-x+x\right)=x-24\)

\(42+0=x-24\)

\(\Rightarrow x=42+24=66\)
