Question

Tìm x 10 - 2(4 -3x) = -4

Answer 1

\(10-2\left(4-3x\right)=-4\)

\(\Leftrightarrow10-8+6x=-4\)

\(\Leftrightarrow2+6x=-4\)

\(\Leftrightarrow6x=-4-2\)

\(\Leftrightarrow6x=-6\)

\(\Leftrightarrow x=\frac{-6}{6}\)

\(\Leftrightarrow x=-1\)

\(\text{Vậy }x=-1\)

Answer 2

10 - 2(4 - 3x)= -4

=> 10 - 8 + 6x = -4

=> 6x = -4 + 8 -10

=> 6x = -6

=> x = -1.

Vậy x = -1

Answer 3

10 - 2( 4 - 3x ) = -4

=> 10 - 8 + 6x = -4

=> ( 10 - 8 + 4 ) = 6x

=> 6 = 6x => x = 1

Answer 4

10-2(4-3x)=-4

2(4-3x)=10-(-4)

2(4-3x)=14

(4-3x)=14/2

4-3x=7

3x=4-7

3x=-3

x=-3/3

x=-1

vậy x = -1

Answer 5

10-2(4-3x)=-4

=>10-8+6x=-4

=> 6x=-2

=> x=-1/3

Answer 6

\(10-2(4-3x)=-4 \)

\(10-2.4-2.3x=-4\)

\(10-8-6x=-4\)

\(2-6x=-4\)

\(6x=2-(-4)\)

\(\Rightarrow x=1\)
