Choose exactly two answers that are correct.

A.
4x – 12

B.
3x – 4

C.
3(2x – 6)

D.
4(x – 5)

Answer 1

can you distribute the 4 in :
4(2x – 3)
(that means multiply 4 times each term inside the parens)

Answer 6

ok

Answer 7

Its B and C.
Let's solve your equation step-by-step.

4x−12=3(2x−6)

Step 1: Simplify both sides of the equation.

4x−12=6x−18

Step 2: Subtract 6x from both sides.

4x−12−6x=6x−18−6x

−2x−12=−18

Step 3: Add 12 to both sides.

−2x−12+12=−18+12

−2x=−6

Step 4: Divide both sides by -2.


−2x
−2
=
−6
−2

x=3



Answer:

x=3
b.
Let's solve your equation step-by-step.

4x−12=3x−4

Step 1: Subtract 3x from both sides.

4x−12−3x=3x−4−3x

x−12=−4

Step 2: Add 12 to both sides.

x−12+12=−4+12

x=8
