Which property of equality would you use in the first step of solving this equation 2x-6=12

1. Add 6 on both sides, under 6 and under 12

2. 6 cancels out

3. Add 12 and 6 to get 18

4. Bring down 2x equal to 18 and divide by 2

5. 2 cancels out

6. 18 divided by 2 equals 9

7. X=9

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
