Question

5x - (24 - 2x) = -24 + 20 + 3x

Answer 1

\(5x-\left(24-2x\right)=\left(-24\right)+20+3x\)

\(5x+\left(-24\right)+2x=\left(-24\right)+20+3x\)

\(7x+\left(-24\right)=\left(-24\right)+20+3x\)

\(7x=20+3x\)

\(\left(7-3\right)x=20\)

\(4x=20\)

\(x=20:4\)

\(x=5\)

Answer 2

5x- (24 - 2x) = -24 + 20 + 3x

5x- 24 + 2x = -4 + 3x

5x + 2x - 3x = 24 - 4

4x = 20

x = 20 \(\div\)4

x = 5

Vậy x = 5

Answer 3

Ta có: \(5x-\left(24-2x\right)=-24+20+3x\)

\(\Leftrightarrow5x-24+2x=-24+20+3x\)

\(\Leftrightarrow5x+2x-3x=24-24+20\)

\(\Leftrightarrow4x=20\)

\(\Leftrightarrow x=\dfrac{20}{4}=5\)

Vậy: \(x=5\)

Answer 4

5x - (24 -2x)= -24+20+3x

=>5x - 24 +2x = -4 +3x

(5x +2x)-24=-4 +3x

7x-24=-4+3x

=>4x-24=-4 (cả 2 vế cùng bớt 3x)

4x=-4+24=20

x=20:4=5

Answer 5

5x - (24 - 2x) = -24 + 20 +3x

\(\Rightarrow\)5x - 24 +2x = -24 + 20 + 3x

\(\Rightarrow \)5x - 3x + 2x = 24 -24 +20

\(\Rightarrow\)4x = 20 \(\Rightarrow \)x = 20:4= 5

Vậy x = 5
