What are the solutions of the equation (x - 3)2 + 2(x - 3) - 8 = 0? Use u substitution to solve.
O x = -5 and x = 1
O x= -1 and x = 5
O x= -1 and x = -7
O x = 1 and x = 7

One number is 4 less than 3 times a second number. if 3 more than two times the first number is decreased by 2 times the second number, the result is 11. use the substitution method. what is the first number?
