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?

6

Step-by-step explanation:

The given equation is

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:

The number that we subtracted from both sides is 6.

6 should be subtracted from both sides of the equality.

Step-by-step 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

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

3x + 2x = 90 {the two angles add up to 90°}
5x = 90 {combined like terms}
x = 18 {divided both sides by 5} 

angle 1 = 3x
= 3(18) {substituted 18, in for x, into 3x}
= 54° angles add up to 90° 

angle 1 = 3x
angle 2 = 2x
