<h3>
Answer:</h3>
These steps <em>can</em> be used:
- combine -6 and 4
- combine 15 and -3
- multiply 2 by x and -2
<h3>
Step-by-step explanation:</h3>
The equation could be solved as follows:
2(x -6 +4) = 15 -3 given
2(x -2) = 15 -3 combine -6 and 4
2(x -2) = 12 combine 15 and -3
2x -4 = 12 multiply 2 by x and -2
2x = 16 add 4 to both sides
x = 8 divide both sides by 2
_____
<em>Alternate solution</em>
At step 4, you could have
x -2 = 6 divide both sides by 2
x = 8 add 2 to both sides
The answer to this question is true. The equation (x-h)^2+(y-k)^2 = r^2 represents a circle with a center at (h,k). Taking (h,k) = (-2,2) and r = 3 results in (x+2)^2 + (y-2)^2 = 9. A negative subtracted by a negative is a positive.
