Explanation
[tex]3(4 - 2x) = - 2x[/tex]
- Distribute 3 in the expression.
[tex]12 - 6x = - 2x[/tex]
- Solve the equation for x-term by making x as the subject.
[tex]12 = - 2x + 6x \\ 12 = 4x \\ \frac{12}{4} = x \\ 3 = x[/tex]
- Answer Check by substituting the value of x in the equation.
[tex]3(4 - 2x) = - 2x \\ 3(4 - 2(3)) = - 2(3) \\ 3(4 - 6) = - 6 \\ 3( - 2) = - 6 \\ - 6 = - 6 \: \: \green{ \checkmark}[/tex]
The equation is true when x = 3. Therefore the answer is D. 3
Answer
[tex] \large \boxed{x = 3} \: \: \sf{or} \: \: \large \boxed{ \sf{D \: \: choice}}[/tex]
