Answer:

A. 2

Explanation:

To find the value of x, first, you have to isolate it on one side of the equation. Isolate x on one side of the equation.

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

4x-5x=-x (Combine like terms and group like terms.)

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

3(2x-4) (Expand.)

DISTRIBUTIVE PROPERTY:

A(B+C)=AB+AC

A(B-C)=AB-AC

3*2x=6x

3*4=12

6x-12

-x+2=6x-12

-x+2-2=6x-12-2 (Subtract 2 from both sides.)

12-2 (Solve.)

12+2=14

-x=6x-14

-x-6x=6x-14-6x (Subtract 6x from both sides.)

-x-6x (Solve.)

-x-6x=-7x

-7x=-14

-7x/-7=-14/-7 (Then, divide by -7 from both sides.)

-14/-7 (Solve.)

-14/-7=2

x=2

Hence, the correct answer is (A.) 2.

Answer:

A

Explanation:

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

-x + 2 = 6x - 12

+x +x

2 = 7x - 12

+12 +12

14 = 7x

/7 /7

2 = x
