Solve. 3=-(-y+6)
a. –9
b. –3
c. 3
d.

3 = -(-y + 6)

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

 y = 9

3=−(−y+6)

Simplify:

3=−(−y+6)

3=y+−6(Distribute)

3=y−6

 Flip the equation.

y−6=3

 Add 6 to both sides.

y−6+6=3+6

y=9
