10*12-3*3=111

428+111=539

8*3*4+3*3=96+9=105

3 = –(–y + 6) a. –9 b. –3 c. 3 d. 9

Vlad1618 [11]

3 = -(-y + 6)

First, simplify brackets. / Your problem should look like: 3 = y - 6
Second, add 6 to both sides. / Your problem should look like: 3 + 6 = y
Third, simplify 3 + 6 to 9. / Your problem should look like: 9 = y
Fourth, switch sides. / Your problem should look like: y = 9

The answer is D) 9.
