Question

In order to isolate the variable term in the equation 6 - 2x = -3 using the subtraction property of equalit

should be subtracted from both sides of the equation?
10 -
O 3
106

Answer 1

6 should be subtracted from both sides of the equality.

Explanation:

The subtraction property of equalities states that if we subtract a number at one side of the equality, we must also subtract the same number at the other side of the equality.

So, in this case, to isolate the variable, we have to subtract 6 from both sides of the equality as follows

`6-2x=-3\\6-6-2x=-3-6\\-2x=-9`

AS you can see, by doing that, we have the variable almost isolated.

Therefore, the answer is 6.

Additionally, is we want to find the solution of the equation, we need to divide each side of the equation by -2

`(-2x)/(-2)=(-9)/(-2)\\ x=(9)/(2)`

Answer 2

6

Explanation:

The given equation is

`6 - 2x = - 3`

In order to isolate the variable term, we need to apply the subtraction property of equality.

We subtract 6 from both sides of the equation to get:

`6 - 6 - 2x = - 3 - 6`

`- 2x = - 9`

The number that we subtracted from both sides is 6.
