Describe the transformation(s) used to solve the equation.
x + 6 = –8
a + 5 = –2
Check if –6 is a solution of 2 – n = 8.
Check if –2 a solution of –3y = 12.
Check if 3 is a solution of 2n + 2 = 8.
Solve.
– 3(a + 5) = 3
6 + 4n = –18
Solve for i.
Solve the equation and check.
5x + 8 = 28
4a + 14 = 8a – 10
20n + 10 = 26
3(x + 7) = –3(x – 5)
