Question

If 5= 5+2x then 12x= ? I’m

Answer 1

Answer:

12x = 0

Step-by-step explanation:

5= 5+2x

Subtract 5 from each side

5-5= 5-5+2x

0 = 2x

Multiply each side by 6

0*6 = 2x*6

0 = 12x

Answer 2

Answer:

12x = 0

Step-by-step explanation:

Let's first find x:

5 = 5 + 2x

Subtract 5 from both sides. Since both sides are equal, subtracting the same from each side will still leave both sides equal.

5 = 5 + 2x

5 - 5 = 5 + 2x - 5

Since 5-5 = 0:

0 = 5 + 2x - 5

0 = 5 - 5 + 2x

Again, 5-5 = 0:

0 = 0 + 2x

0 = 2x

Dividing both sides by 2:

0/2 = 2x / 2

0 = x

x = 0

As we can see, x = 0.

Thus, 12x must also be 0:

12x

Putting in x = 0:

12 * 0 = 0

Answer: 12x = 0
