Question

Solve for x.
3 (4-2x) = -2x
A)-1
B)1
C)2
D)3

Answer 1

solution

Explanation:

3 (4-2x)= -2x

12-6x= -2x

12= -2x+6x

12= 4x

12÷4= x

3= x

D

Answer 2

Explanation

• Given the equation.

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

• Distribute 3 in the expression.

`12 - 6x = - 2x`

• Solve the equation for x-term by making x as the subject.

`12 = - 2x + 6x \\ 12 = 4x \\ (12)/(4) = x \\ 3 = x`

• Answer Check by substituting the value of x in the equation.

`3(4 - 2x) = - 2x \\ 3(4 - 2(3)) = - 2(3) \\ 3(4 - 6) = - 6 \\ 3( - 2) = - 6 \\ - 6 = - 6 \: \: \green{ \checkmark}`

The equation is true when x = 3. Therefore the answer is D. 3

Answer

`\large \boxed{x = 3} \: \: \sf{or} \: \: \large \boxed{ \sf{D \: \: choice}}`
