Hey!
--------------------------------------------------
Solve 2(x + 7) = 28 with x = 7.
2(7 + 7) = 28
2(14) = 28
28 = 28
TRUE
--------------------------------------------------
Solve 60 = 4(x + 8) with x = 7.
60 = 4(7 + 8)
60 = 4(15)
60 = 60
TRUE
--------------------------------------------------
Solve 6(2x - 1) - 12 = -2(x + 10) with x = 7.
6(2(7) - 1) - 12 = -2(7 + 10)
6(14 - 1) - 12 = -2(17)
6(13) - 12 = -2(17)
78 - 12 = -34
66 ≠ -34
FALSE
--------------------------------------------------
Solve 3(x - 5) = 1 + 5(x - 6) with x = 7.
3(7 - 5) = 1 + 5(7 - 6)
3(2) = 1 + 5(1)
6 = 1 + 5
6 = 6
TRUE
--------------------------------------------------
Hence, the correct answers are A, B, and D!
--------------------------------------------------
Hope This Helped! Good Luck!
